Calibration Access and Data Handbook

SAS processing

SAS processing with the latest software and CCF files is performed as follows

• Generation of filtered event files, source lists and extracted spectra for ONAXIS coordinates

  rgsproc xpsfincl=100 pdistincl=95 finalstage=2:angles
  rgssources srclist=P0123450101RXS099SRCLI_0000.FIT changeprime=yes \
             primelabel='ONAXIS'
  rgsproc entrystage=2:angles finalstage=4:spectra
  

• Generation of background light curves

  evselect table=P0123450101RXS099EVENLI0000.FIT \
           expression=((XDSP_CORR<-3.E-4)||(XDSP_CORR>3.E-4))&&(CCDNR==9) \
           filtertype=expression rateset=rateRXS099.fits \
           timecolumn=TIME timebinsize=100 maketimecolumn=yes \
           tmakeratecolumn=yes withrateset=yes
  

• Generation of GTIs for each of the 16 pre-defined background levels
  • if no there are no data for some levels their GTIs will be empty

  tabgtigen table=rateRXS099.fits gtiset=rR1S004_Y.YY.fits \
            expression='RATE > Y.YY && RATE <= Z.ZZ' \
            timecolumn='TIME'
  

• Generation of filtered event files for each of the 16 pre-defined background levels

  rgsfilter mergedset=P0123450101RXS099EVENLI0000.FIT \
            evlist=RXS099_Y.YY.FIT \
            auxgtitables=rRXS099_Y.YY.fits \
            withcombmap=no
  

• Extraction of spectra from each of the filtered event files for
  • 1st and 2nd order
  • PI extraction regions 90 and 95%

  rgsspectrum evlist=RXS099_Y.YY.FIT srclist=RX_SRCLI_XX.FIT \
              bkgcorrect=no spectrumset=RXS099SPEC_Y.YY.FIT \
              withbkgset=no source=2 order=1
