Hello,

I used sherpa to model the morphology of a compact source observed by XMM
assuming it follows a King profile, as described in Ghizzardi and Molendi 2002. 
The numbers I get imply a steeper PSF than the PSF quoted in their paper.  I was
wondering if they are any updated values for the core radius and alpha for these
instruments?  Thanks -- Yosi

Hello Yosi, 

the latest project updates on EPIC PSF's can be found at

http://xmm.esac.esa.int/docs/documents/CAL-TN-0018.pdf

and in the latest CCFs:

XRT1_XPSF_0007.CCF and XRT2_XPSF_0007.CCF

Sincerely,

Pedro
