epevents (epevents-6.55) [xmmsas_20230412_1735-21.0.0]

Examples

Let us assume we have an output event file produced by epframes and badpix with name rawevents_04.dat, then the simplest call to epevents is

  epevents eventset=rawevents_04.dat outset=events_04.dat

If you want to produce a diagnostic file containing CCD maps in 4 energy bands in the same run then you may use

  epevents eventset=rawevents_04.dat outset=events_04.dat \
    withphotonmap=Y photonmapset=eventmap_04.dat          \
    lothresh="0 200 500 0" hithresh="200 500 2000 32000"  \
    mappatterntype=sssn

This creates three maps with single events only ($0-0.2$ keV, $0.2-0.5$ keV, $0.5-2.0$ keV) and one with all non-single events in the energy range $0-32$ keV. The parameters lothresh, hithresh, and mappatterntype are used with default values. A non-default call is

  epevents eventset=rawevents_04.dat outset=events_04.dat \
    withphotonmap=Y photonmapset=eventmap_04.dat          \
    lothresh="0 0 0 0" hithresh="32000 32000 32000 32000"  \
    mappatterntype=sxvw

which creates one single events map, one with doubles perpendicular to the readout direction, and two maps with doubles in readout direction where one has the main event near the CAMEX and the other with the main away from the CAMEX.
