Hi,

Can you please tell me if the problem you see is with the coordinates or with the
shape of the PSF?
Also, could you please give me more info (date and idetification number)
on the e-mail in the Chandra email archive that hasn't been replied
so I can take a look at the problem.
Thanks,
Margarita Karovska
