NAME

USAGE

DESCRIPTION

hxipipeline duplicates most of the pipeline (not trend data) for the hxi. It allows the user to run all or part of the pipeline processing and to vary the calibration files and filtering (screening) criteria used. A number of other pipeline processing parameters can also be changed.

HXI Pipeline Stages

The hxipipeline is divided into 3 stages:

1. Calibration
2. Data screening
3. Product creation

HXI Stage 1 consists of the following ordered steps:

1. Run cams2att*
2. Run hxisgdsff
3. Run hxisgdpha
4. Run hxievtid
5. Run coordevt

*Note: cams2att us automatically run twice. Once with parameters set for HXI1, the other with paramaters set for HXI2.

The data screening (Stage 2) is identical to that in the production pipeline, when default parameters are used. For details on the default screening applied to the HXI events (respectively), see:

• ahfilter - Create the EHK from attitude & orbital data and create the MKF from housekeeping data based on the CALDB mkfconf file
• ahgtigen - Create the GTI from the EHK and MKF parameters based on CALDB selection file
• ahscreen - Screen the data based on GTI and CALDB selection file

Default GTI used for screening data are:

• GTIPOINT
• GTITEL
• GTIEHK
• GTIMKF

The product creation (Stage 3) is identical to that in the production pipeline, when default parameters are used. For HXI events extractor is run on SKY coordinates and a lightcurve, spectra and images are created for each cleaned event file.

INPUT

The input to hxipipeline is specified using (at minimum) the indir parameter. This should be specified as the hxi event_uf level sequence directory, e.g.:

hxipipeline indir=/path/to/100039010/hxi/event_uf

Paths to specific hxi housekeeping and satellite data files can be specified using the attitude, housekeeping, extended_housekeeping, makefilter, orbit and obsgti parameters. The attitude, orbit and hxi housekeeping files are required for stage 1 calibration.

OUTPUT

Filenames, etc.

The number of output files depends on both pipeline processing stage(s) and the options selected. All output files are written to the directory specified by the outdir parameter. The archive directory structure is NOT reproduced (i.e. all output files is in a single directory).

The names of files produced are the same as those found in the HEASARC archive. However the usual "ahXXXXXXXXX" prefix, where "XXXXXXXXX" is the sequence number, can be replaced by a character string set by the stemoutputs parameter. This defaults to the value set by the steminputs parameter.

cams2att:

Name of filtered, temperature-corrected CAMS1 displacement file. This file is written by the tool ftselect in Step 2, and it is read by the tool cams2det in Step 3. If startstep=1 or 2, then specifying "NONE" causes the file to be given the name tmp_prefiltfile1.fits and to be deleted if cleanup=yes.

(coordevt_startsys = LOWEST) [string]

coordevt:

Sets starting coordinate system specifically for coordevt.

The name of the coordinate system from which the coordinate conversions begin. If startsys=LOWEST, then the coordinate transformation begins with the lowest level system in the teldef file (COORD0; usually RAW). The startsys and stopsys parameters work together to specify the origin (startsys) and final (stopsys) systems. Setting startsys=LOWEST and stopsys=HIGHEST the task converts the bottom-level coordinates into all the other coordinate systems. It is allowed for startsys to be a higher level coordinate system than stopsys. For example, setting startsys=HIGHEST and stopsys=LOWEST converts the top-level coordinates into all the other coordinate systems.

(stopsys = HIGHEST) [string]

coordevt:

The name of the coordinate system at which the coordinate conversions end. If stopsys=HIGHEST, then the coordinate transformation chain ends with the highest level system (SKY). See also the description of the startsys parameter.

(annaber = no) [string]

coordevt:

If YES, the effects of annual aberration are taken into account when calculating the SKY coordinate values. Annual aberration is the apparent bending of light due to the Earth's orbit around the Sun. This is at most a ~20.49 arcsec effect. If INVERT, the sign of the annual aberration correction is flipped before being applied to the sky coordinates. This is used for debugging. If NO, the annual aberration is not corrected.

(followsun = no) [boolean]

coordevt:

Should aberration be recalculated for each event time? If set to "no" the aberration at the time given by the MJDOBS keyword is used for all events. Setting this to "no" is acceptable except for very long observations, and this makes the program run slightly faster. The "yes" setting should be used for highest accuracy, and this setting uses the MJDREF keyword (or pair of MJDREFI and MJFREFF keywords) along with the TIME column of the event extension to calculate absolute event times.

(orbaber = no) [string]

coordevt:

If YES, the effects of orbital aberration are taken into account when calculating the SKY coordinate values. Orbital aberration is the apparent bending of light due to the satellite's orbit around the Earth. For a satellite in low-earth orbit, this is at most a ~5 arcsec effect. If INVERT, the sign of the orbital aberration correction is flipped before being applied to the sky coordinates. This is used for debugging. If NO, the orbital aberration is not corrected.

(attinterp = LINEAR) [string]

coordevt:

Spacecraft attitude interpolation method. The value LINEAR results in the attitude being linearly interpolated to the event time. The value CONSTANT results in the attitude being taken from the nearest attitude record.

(dattinterp = LINEAR) [string]

coordevt:

Delta attitude interpolation method. The value LINEAR results in the delta attitude being linearly interpolated to the event time. The value CONSTANT results in the delta attitude being taken from the nearest attitude record.

(attdt = 32.) [real]

coordevt:

Allowed time in seconds to extrapolate the spacecraft attitude before the first or after the last row in the attitude file. Events beyond this time margin have their coordinates set to a null value.

(dattdt = 0.5) [real]

coordevt:

Allowed time in seconds to extrapolate the auxiliary ("delta") attitude before the first or after the last row in the attitude file. Events beyond this time margin have their coordinates set to a null value.

(chkattgap = no) [boolean]

coordevt:

Set this parameter to "yes" to use the attdt also for interpolation. Event times that fall within the sky attitude time range but not within the attdt of the nearest attitude time are set to null. Set chkattgap to "no" to always interpolate the attitude at the event time. The attdt value is used for extrapolation regardless of the value of chkattgap.

(chkdattgap = yes) [boolean]

coordevt:

Set this parameter to "yes" to use the dattdt also for interpolation. Event times that fall within the delta attitude time range but not within the dattdt of the nearest attitude time are set to null. Set chkdattgap to "no" to always interpolate the attitude at the event time. The dattdt value is used for extrapolation regardless of the value of chkdattgap.

(attext = ATTITUDE) [string]

coordevt:

The name of the FITS attitude file extension containing satellite attitude data.

(attcol = QPARAM) [string]

coordevt:

The name of the FITS column containing attitude values as a vector in the attext extension of the attitude table.

(attform = QUAT) [string]

coordevt:

The format in which the attitude is provided in the attitude table. Two formats are supported. The QUAT format is a quaternion [x, y, z, real]. The EULER format is a Z-Y-Z Euler angle trio [phi, theta, psi] in degrees.

(orbext = ORBIT) [string]

coordevt:

The name of the FITS orbit file extension containing satellite orbit data.

(orbcol = VELOCITY) [string]

coordevt:

The name(s) of the FITS column(s) containing orbit values in the orbext extension of the orbit file. If orbform="VECTOR", then orbcol is the name of the single FITS column containing the orbit values as a vector. If orbform="COMPONENTS", then orbcol must be a string containing three comma-separated column names, specifying in order the X, Y and Z components of the orbital velocity.

(orbform = VECTOR) [string]

coordevt:

The format in which the orbital velocity is provided in the orbit file. Two formats are supported. For the VECTOR format, the velocity is provided as a vector column with three elements (X, Y and Z in Earth-Centered Inertial (ECI) system). For the COMPONENT format, the velocity is provided in three separate columns.

(coordevt_randomize = TELDEF) [string]

coordevt:

Set randomize coordinates specifically for coordevt.

If this parameter is set to "no", coordevt assumes that each event occurred at the center of its coordinate pixel. If it is set to "yes", the coordinates from system randsys onward is calculated assuming a random location within the randsys system pixel. If randomize="CALDB", then randomization is enabled (RANCOORD != 'NONE') or disabled (RANCOORD = 'NONE') depending on the TelDef keyword RANCOORD. This parameter only controls randomization in transformations previous to the transformation to the SKY system.

(randsys = TELDEF) [string]

coordevt:

The name of the starting coordinate system for which randomization is performed, as long as randomization is enabled by the randomize parameter. If randsys="CALDB", the value of the RANCOORD keyword (if present) of the TelDef file specifies this system.

(randscalesys = TELDEF) [string]

coordevt:

The name of the coordinate system whose pixels determine the size of the randomization if randomization is enabled by the randomize parameter. If randscalesys="CALDB", the value of the RAN_SCAL keyword of the TelDef file is used if the keyword is present, and the value of the randsys parameter is used if the RAN_SCAL keyword is not present. It is most common for randsys and randscalsys to be the same coordinate system, but it is not required.

(infileext = EVENTS) [string]

coordevt:

The name of the infile extension containing the event table.

(timecol = TIME) [string]

coordevt:

The name of the FITS column in the event table containing time values.

(inclfloatcol = no) [boolean]

coordevt:

If this parameter is set to "yes", an additional column of unrounded coordinate values is included in the output event file for each coordinate of each system after the startsys system. Enabling this parameter is useful for stringing multiple coordevt runs together (e.g., convert RAW to DET in one run and DET to SKY in a second run) without loss of precision due to the normal rounding of coordinates. Use startwithfloat="yes" for runs after the first so that the unrounded coordinates from the previous coordevt run are used as the starting coordinate values for a subsequent run. Rounded coordinate columns are written regardless of the value of this parameter. Unrounded SKY coordinate columns are included if either of inclfloatcol or inclfloatskycol is set to "yes".

(inclfloatskycol = no) [boolean]

coordevt:

If this parameter is set to "yes", an additional column of unrounded coordinate values is included in the output event file for each SKY coordinate. Rounded SKY coordinate columns are included regardless of the value of this parameter. Unrounded SKY coordinate columns are included if either of inclfloatcol or inclfloatskycol is set to "yes".

(floatcolsuffix = _FLOAT) [string]

coordevt:

This parameter sets the suffix used in all unrounded coordinate column names. If the rounded coordinate column name is DETX and floatcolsuffix=_FLOAT, then the corresponding unrounded coordinate column name is DETX_FLOAT. This parameter is used only when either of inclfloatcol or inclfloatskycol is set to "yes".

(startwithfloat = no) [boolean]

coordevt:

This parameter is set to "yes" to use the unrounded coordinate column values (e.g., floating point values from DETX_FLOAT and DETY_FLOAT columns) as the starting coordinate columns. Enabling this parameter is useful for non-initial runs of coordevt in a string of runs that each convert between a subset of the transformations. The inclfloatcol parameter must be set to "yes" for startwithfloat to have an effect. When either of inclfloatcol or startwithfloat is disabled, rounded coordinate values (e.g., integer values from DETX and DETY columns) are used as the starting coordinate values.

(blankcol = yes) [boolean]

coordevt:

This parameter is set to "yes" to fill the coordinate columns after the stopsys coordinate system with NULL values. If blankcol is set to "no", such columns are not changed. The behavior is somewhat different depending on what coordinate columns already exist in the input file. If columns for coordinates beyond the stopsys coordinate system exist in the input file, then when blankcol="yes", their values are replaced with NULL values and when blankcol="no", their values are copied to the output file unchanged. If, however, such columns do not already exist in the input file, then they are created and filled with NULL values when blankcol="yes", but not created if blankcol="no".

(btnull¹ = 255) [integer]

coordevt:

This parameter sets the null integer value for any output unsigned byte (TFORM = "1B") coordinate columns that are missing or lack the TNULL keyword in the input event file.

(itnull¹ = -999) [integer]

coordevt:

This parameter sets the null integer value for any output short integer (TFORM = "1I") coordinate columns that are missing or lack the TNULL keyword in the input event file.

(jtnull¹ = -999) [integer]

coordevt:

This parameter sets the null integer value for any output long integer (TFORM = "1J") coordinate columns that are missing or lack the TNULL keyword in the input event file.

(ktnull¹ = -999) [integer]

coordevt:

This parameter sets the null integer value for any output long integer (TFORM = "1K") coordinate columns that are missing or lack the TNULL keyword in the input event file.

(sbtnull¹ = 255) [integer]

coordevt:

This parameter sets the null integer value for any output signed byte (TFORM = "1B" with TZERO = -128) coordinate columns that are missing or lack the TNULL keyword in the input event file. The specified null value is the value to be stored in the FITS file, not the value in the signed domain.

(uitnull¹ = -999) [integer]

coordevt:

This parameter sets the null integer value for any output unsigned short integer (TFORM = "1I" with TZERO = 32768) coordinate columns that are missing or lack the TNULL keyword in the input event file. The specified null value is the value to be stored in the FITS file, not the value in the unsigned domain.

(ujtnull¹ = -999) [integer]

coordevt:

This parameter sets the null integer value for any output unsigned long integer (TFORM = "1J" with TZERO = 2147483648) coordinate columns that are missing or lack the TNULL keyword in the input event file. The specified null value is the value to be stored in the FITS file, not the value in the unsigned domain.

(occurrenceid = -1) [integer]

hxievtid:

If greater than zero, only expand this single occurrence.

(seed = 0) [integer]

coordevt/cams2att:

Random number generator seed to be used if randomization is enabled. For a given seed value, the same results are produced each time the program is run.

(stemreport = ) [string]

File stem for log and temporary files. If the parameter is not set the script automatically sets the stem to "hxipipeline_YYYYMMDDTHHMMSS_" and appends log file and temp file names as needed. Intended to be set by ahpipeline.

(numerrs = 0) [string]

Number of errors from hxipipeline (output)

(cleanup = yes) [boolean]

Delete temporary files ([yes]/no)

(clobber = no) [boolean]

Overwrites the existing output file if set to yes (yes/[no]).

(chatter = 1) [integer]

Chatter level for output. Set to 0 to suppress output, or to 1, 2, or 3 for increasing the chatter of the output.

(logfile = !DEFAULT) [string]

Log filename. If set to DEFAULT uses the name of the task and, if preceded by '!', overwrite the file if it exists. If set to NONE no log file is created.

(debug = no) [boolean]

Diagnostic output is printed out on the screen if set to yes (yes/[no]).

(history = yes) [boolean]

Records tool parameters in HISTORY ([yes]/no).

(mode = ql) [string ql|hl|q]

Mode to query the parameter file. Acceptable values include: 'ql' (query and learn/remember), 'hl' (hidden and learn/remember), 'q' (query but don't remember)\ , 'h' (hidden).

¹These parameters are used to specify default null value processing. Null values may appear for several reasons, including the following: 1. the event time cannot be matched to a row of an attitude file within the time margin; 2. the coordinate system is subsequent to the stopsys coordinate system and blankcol is enabled; 3. a calculated coordinate is outside the allowed range of that coordinate. If an output column already exists in the input file and TNULL for that column is specified in the event file header, then the existing TNULL keyword is copied to the output column. If, however, the output column does not exist in the input file or the column exists, but does not have an associated TNULL keyword, then the appropriate nullvalue parameter is used.

If a list of files is needed, they can be entered one per line in a text file, and then dattfiles should be set to that text filename prefixed with "@", for example dattfiles = "@dattfiles.txt". A delta-attitude file must be provided for each coordinate transformation of type 'SKYATT' in the teldef file, with the exception of the transformation to the SKY system. The delta-attitude must be in quaternion format.

(orbfile = NONE) [filename]

Set to the hxipipeline orbit parameter (see above)

AHGTIGEN:

mkffile [filename]

Set to the makefiler file parameter the first time ahgtigen runs.

Set to the extended_housekeeping file parameter the second time ahgtigen runs (unless the files being generated are pseudo event files).

outfile [filename]

Set to ${hxifile_out} . gtimkf, when the input file is set to the makefiler file parameter.

Set to ${hxifile_out} . gtiehk, when the input file is set to the extended_housekeeping file parameter.

(instrume = NONE) [string]

(HXI1 or HXI2) Read from the header of the file being processed.

(label = NONE) [string]

HXISFFA1CAM or HXISFFA1PSE depending on if the files being generated are "clean" or "pseudo" respectively.

AHSCREEN:

infile [string]

Set systematically to the elements in an array which is constructed from any reconstructed unfiltered event files produced in the calibration stage.

If the calibration stage is being skipped, this array is filled from searching the input directory instead.

outfile [filename]

Set to the same name as infile, but in the outdir directory and changing the extension from "rec_ufa.evt" to "rec_cl.evt".

(gtifile) [string]

Set as an array of gtifiles with corresponding extensions; pointing, tel, mkf, and (where applicable) ehk.

(upkeyword = YES) [boolean]

Update timing keywords from input file(s) in output file

Hardcoded as yes

(label = NONE) [string]

HXISFFA1CAM or HXISFFA1PSE depending on if the files being generated are "clean" or "pseudo" respectively.

EXAMPLES

1. The following command recalibrates (stage 1) and re-screens (stage 2) all HXI data for sequence 100039010 that currently resides in the directory /data/100039010/hxi/event_uf, and the output is stored in a directory called /data/100039010_reproc/:

   hxipipeline indir=/data/100039010/hxi/event_uf outdir=/data/100039010_reproc entry_stage=1 exit_stage=2 steminputs=ah100039010 attitude=/data/100039010/auxil/ah100039010/ah100039010.att orbit=/data/100039010/auxil/ah100039010/ah100039010.orb obsgti=/data/100039010/auxil/ah100039010/ah100039010_gen.gti makefilter=/data/100039010/auxil/ah100039010/ah100039010.mkf exended_housekeeping=/data/100039010/auxil/ah100039010/ah100039010.ehk

2. The following command re-screens (stage 2 only) HXI data for the same data set as in the previous example.

   hxipipeline indir=/data/100039010/hxi/event_uf outdir=/data/100039010_reproc entry_stage=2 exit_stage=2 steminputs=ah100039010 obsgti=/data/100039010/auxil/ah100039010/ah100039010_gen.gti makefilter=/data/100039010/auxil/ah100039010/ah100039010.mkf exended_housekeeping=/data/100039010/auxil/ah100039010/ah100039010.ehk

3. The following command creates products (stage 3 only) HXI data for a calibrated data set:

   hxipipeline indir=/data/100039010/hxi/event_cl outdir=/data/100039010_reproc entry_stage=3 exit_stage=3 steminputs=ah100039010 regionfile=none

NOTES

None, but see help for individual parameters above.
