Hello everyone:

When I run "erbox" on the events after removing the data from TM5 and TM7, it doesn't work.



erbox: eSASS4EDR Feb 23 10:30:53 2022
erbox/SORT_IMA: **ERROR3** No detection mask for exposure

Hi,

The error seems to indicate that you are not providing a detection mask, i.e. by using the "detmasks" option that erbox requires.

Please copy and paste the whole command you are trying to execute so it is easy for us to understand better your problem.

Best wishes,

Here are the commands:

evtool eventfiles="../fm00_300007_020_EventList_c001.fits" outfile="events_image_300007.fits" image=yes emin=0.5 emax=2.0 region="fk5;circle(128.35,1,2.8)";

radec2xy "events_image_300007.fits" "128.35" "1";

evtool eventfiles="events_image_300007.fits" outfile="events_image_300007.fits" image=yes emin=0.5 emax=2.0 center_position="0 0" telid='1 2 3 4 6';

expmap inputdatasets="events_image_300007.fits" emin=0.5 emax=2.0 templateimage="events_image_300007.fits" mergedmaps="output_expmap_300007.fits";

ermask expimage="output_expmap_300007.fits" detmask="detmask_300007.fits";

erbox images="events_image_300007.fits" boxlist="boxlist_local_300007.fits" emin=500 emax=2000 expimages="output_expmap_300007.fits" detmasks="detmask_300007.fits" bkgima_flag=N ecf=1;

HI,

At first glance, I see an error: radec2xy does not work on images, but in event files (see https://erosita.mpe.mpg.de/edr/DataAnal ... ub_Point_6). Before creating an image you must recenter your event file.

Best wishes,

Hi,

Indeed, it worked if adopting all of the TMs.
