HXTRSP 3.2 NAME hxtrsp - produce a HEXTE response matrix for a HEXTE spectrum (PHA file) USAGE hxtrsp [-i "pha_file"] [-a "attitude_file"] [-h] If the "pha_file" or "attitude_file" are not present, the user is prompted for them. DESCRIPTION This is a Perl script. For a HEXTE spectrum it uses the calibration data stored in the OGIP Calibration Database ("CALDB") to form an appropriate response matrix, based on the "detector ID" of the spectrum, the observation date, and an optional XTE Filter file or attitude file for calculating the collimator response. (If not provided, the Ftool HXTARF is called in any case to calculate the collimator response at the nominal RXTE boresight). The resulting response matrix is named after the root name of the PHA file with the suffix ".rsp". If the detector ID and date/time are not present in the PHA file as FITS keywords, the user is prompted for their values (which are subsequently written into the PHA file, along with a RESPFILE keyword identifying the new response matrix which HXTRSP created). PARAMETERS -i pha_file: A spectral file produced by SEEXTRCT/SAEXTRCT, optionally corrected for dead-time by HXTDEAD. -a attitude_file: An RXTE attitude file (FH0e_*), or an RXTE filter file containing spacecraft attitude data for the observation. Either file must contain data covering the start and stop times of the PHA file. If the user specifies 'NONE', then HXTARF assumes that the observation was made at the RXTE nominal boresight position; type "fhelp hxtarf" for more details. Ftools called by this script: ----------------------------- quzcif, fkeypar, pget, rddescr, rbnrmf, hxtarf, marfrmf, fparkey CALDB datasets required: ------------------------ "MATRIX", "COLLRESP", "EFF_AREA" datasets are all required to be defined for the HEXTE, the last two are for use with HXTARF. EXAMPLES 1. hxtrsp -i FS50_xxx.pha -a xtefilt.xfl This produces a HEXTE matrix called FS50_xxx.rsp suitable for the PHA file. An RXTE filter file is used for the spacecraft pointing data, which is compared to the RA_OBJ and DEC_OBJ keywords in the input PHA file. 2. hxtrsp -a NONE The user has specified that no spacecraft pointing data be used. HXTRSP will prompt for the name of the input PHA file. 3. hxtrsp -h | more Prints this help information. SEE ALSO hxtarf, rddescr, caldb
