Hi,
From the apetool documentation one can read "The PSF of the eROSITA is modeled using shapelet functions and their corresponding coefficients. This shapelet model, stored in an appropriate calibration file, describes how the shape of the PSF changes as function of energy and position on the eROSITA field of view."
Where can one find this PSF shapelet model?
Thank you very much in advance.
Best regards,
Matteo

Re: Point Spread Function
Dear Matteo
the shapelet PSF model are located in the caldb :
in the subfolders :
data/erosita/tm[telID]/bcf/tm[telID]_slet_psf_XXXXXXvXX.fits
the main folder of the caldb on your installation is stored in the environment variable $CALDB
so the location of the various PSF models are in
$CALDB/data/erosita/tm[telID]/bcf/tm[telID]_slet_psf_XXXXXXvXX.fits
Hope this help
Regards
Alain
