Input Files

1. expmapset: a template image which is of the same dimensions and coordinates as the images and exposure maps which were supplied to eboxdetect. The dataset header must contain the following keywords:
   • INSTRUME (must be either EMOS1, EMOS2 or EPN).

   • RA_PNT, DEC_PNT, PA_PNT: the spacecraft mean attitude (should be the instrument attitude!) in decimal degrees.

   • DATE-OBS

   The image array header must in addition contain WCS keywords.

   Note that esensitivity passes to parameter expmapset the exposure map in the appropriate energy band which was supplied to the -expimagesets parameter of eboxdetect. This dataset type is expected to meet the above criteria.

2. (optional) dssimageset: this dataset is read if psfestyle=`dss'. It should contain an event image in the primary array, which has an associated data subspace recording the event selections which were performed. The image in the appropriate band supplied to the -imagesets parameter of eboxdetect is recommended.
