ROSAT Status#139 - Updated Master Observation List
ROSAT Status Report #139
April 18 1996
UPDATED ROSAT Master Observation List
The latest ROSAT Master Observation Log files can now be found in the
ROSAT anonymous FTP are under the directory: /rosat/timelines/
below is a copy of the masterlog.README file explaining the contents
of the files.
The master observation log combines all available information about all
ROSAT observations to date into one "masterlog" data base. Due to the
length and nature of the data, two listings are offered, one of which is
broken into two separate files for ease of transport.
Observation sequences are included starting from their appearance in a
short-term time line (the list of observations telemetered to the
satellite). At this stage, the observation should be done but there always
exists the possibility of satellite failure or lack of target aquisition
which will affect exposure times. Because of this, final information can
only be achieved after the observations have been processed by SASS and
the list made complete only a few months after an observation has been
finished. In producing this log, several files were merged and cross
correlated, with not always consistent results. We have made every effort
to understand and eliminate any known inconsistencies, however, please
contact the ROSAT GOF if any errors are found.
File Names and Sizes:
masterlog1_1-5 1232455 bytes
masterlog1_6-9 1102428 bytes
masterlog2 1027478 bytes
These files were compiled from:
masterlog_mpe.960311 (from MPE)
rospublic (96.099) (from BROWSE at GSFC)
rosatlog (96.096) " "
rosdistrib (96.094) " "
In addition this directory also contains the latest master log
file from MPE.
masterlog_mpe.960311 652901 bytes (1996, March, 11)
If there is a discrepancy between the masterlog#_#-# files and the
masterlog_mpe.yymmdd file, the MPE file should take precedence.
Broken into two files by ROR number, for reasons of length.
masterlog1_1-5 = ROR's 1 - 599999
masterlog1_6-9 = ROR's 600001 - 999999
Indexed by ROR number, May have multiple lines of data per ROR
due to re-observations (extensions added) and filtered/unfiltered
observations of the same target receiving the same ROR number.
The files contain the following information:
ROR Instrument Earth_Ang Target # PI_Lname
Object name RA Sun_Ang AO
PI # DEC Constraints Country
ROSAT_day LII Night Class
Requested_exposure BII WF_Flt Dist_Date
Exposure Zoom X offset Public_Date
Completion Flag Solar_Ang Y offset Seq_ID
Indexed by RA, it is a subset of Masterlog1, and may have multiple
lines of data per ROR due to re-observations (extensions added)
and filtered/unfiltered observations of the same target receiving
the same ROR number.
This file contains the following information for ALL ROR's:
ROR RA Distribution_Date
Name DEC Completion Flag
PI_Lname Requested_Exposure Public_Date
Instrument Exposure Sequence_ID
KEY to Listings (Masterlog1 and Masterlog2)
ROR = The ROSAT observation request sequence number.
NAME = The name of the target.
PI_# = The Principal Investigator number.
RDAY = The ROSAT day number at the start of the pointing (2 June 1990
has RDAY = 1). ROSAT day numbers between 1 and 60 are from the
performance verification (PV) phase, while day numbers greater
than ~256 are from the AO1 phase.
REQ_EXPS = The requested exposure time in ksec.
EXPOSURE = The exposure time in ksec.
** PLEASE NOTE: The `duration` shown here indicates only the
length of time that the telescope pointed in a certain direction;
it is NOT a total observation time. Operational or other
problems may have occurred during the pointing which would cause
the total observation time to be less than the `duration` given
here. The masterlog_mpe.yymmdd file provides the total SASS
processed exposure times for GO observations.
F = Observation complete ('Y' if >= 70% of requested time completed)
INST = The prime instrument for this observation.
RA = The RA in J2000 coordinates.
DEC = The DEC in J2000 coordinates.
LII = Galactic Longitude
BII = Galactic Latitude
ZOOM = Is the wide field camera zoom mode switched on for this
SOL_ANG = The solar aspect angle at the PREDICTED start of the
ER_ANG = The minimum Earth angle at the PREDICTED start of the
SU_ANG = The mean angle between the Sun and the spacecraft at the
PREDICTED start of the observation.
CONSTR = The type of time constraint under which the observation was
scheduled, if any (i.e., monitoring observation, phase-dependent
observation, coordinated observation, or contiguous observation).
NGHT = Percentage of the PREDICTED observation slot that the spacecraft
spends in the Earth's shadow.
WF_FLT = The Wide Field Camera filter used for the observation.
XOFF = X pointing offset.
YOFF = Y pointing offset.
XFT = The XRT filter wheel position (Open, Boron, or Closed). During
reduced pointing mode (RORs 171nnn) the filter may be in the
open position for some fraction of the observing slot even if
the filter position is given as closed.
T# = The target number.
AO = The proposal announcement of opportunity.
CC = The originating country for this ROSAT Observation Request.
CLASS = BROWSE classification flag.
DIS_DATE = The date that the data were distributed to the Principal
PUB_DATE = The date the observation was made public (yy.ddd).
SEQ_ID = sequence id (archive file name)
PI_LNAME = The last name of the principal investigator.
