psfgen (psfgen-1.7.1) [xmmsas_20230412_1735-21.0.0]

Comments

• psfgen produces the PSF image(s) at the specific position in TEL.
• psfgen creates a PSF image for each energy value in energy list and one summation PSF image using the weightings. Therefore, if there $n$ energy values in the list, $n+1$ PSF images will be created, except for $n=1$, which only one image will be created.
• The first PSF image is always the summation PSF image. Other PSF images are named with their energy values. All PSF images are saved in one fits file.
