Hmm, this gets me started. I'll try your suggestions for Sherpa. But in the
meantime I have a couple of further questions regarding what you said about
pile-up:

I'm a bit lost here: how do you propose I modify my PSF file for pile-up?
Also it seems to me that doing things this way would force one into assuming
that all sources have exactly the same fraction of piled-up pohtons. This
isn't the case in my data: there are four sources affected by pile-up, with
fluxes (and presumably piled-up fractions) that vary by about a factor 4.
Thanks,
Eric
