badpixfind (badpixfind-1.41) [xmmsas_20230412_1735-21.0.0]

Examples

• badpixfind eventset=mosevents.dat (default automatic MOS PPS setting)

• badpixfind narrowerthanpsf=1.5 backgroundrate=0.0001 hithresh=0.0045 hicolthresh=0.00105 withsearchbadcolumn=y loenergythresh=0.14 hienergythresh=10.0 eventset=pnevents.dat (recommended automatic PN PPS setting)

• badpixfind eventset=mosevents.dat thresholdlabel=peak backgroundrate=-1 hithresh=90 flickertimesteps=5 flickerksthresh=0.52 flickerchisqthresh=12 (bad pixels brighter than 90% of the peak brightness are searched for, as are flickering pixels with variabilities in excess of the given flicker thresholds)

• badpixfind eventset=mosevents.dat searchbadpix=n userflagbadpix=y rawxlist="3 6" rawylist="5 8" typelist="4 4" yextentlist="2 2" badpixset=bpxfmos.fits (just mode 2 (explicit user flagging) is used to create two entries in output file bpxfmos.fits)

• badpixfind eventset=pnevents.dat threshabovebackground=Y withbadpixmap=Y hithresh=0.00025 withsearchbadcolumn=y hicolthresh=0.00007 backgroundrate=-1 loenergythresh=7.0 hienergythresh=15.0 narrowerthanpsf=0.0 withfovmask=Y (detects bad pixels/columns and also sources in a hard energy band, the thresholds set according to a calculated background level, producing a background mask [badpixmap.fits] with the FOV masked out, usable (in evselect) to create a background spectrum/lightcurve etc)
