Wings of Chandra Point Spread Function

Dear Co-Users

I am analyzing the data of a strong X-Ray source. After determining the
spectrum of the source, I subtracted the Marx-estimate of the source
emission from the data and a statistically highly significant residuum
remains with an event excess at 15''-50'' angular distances from the
source.

Has anybody used in-flight data to compare the wings of the point spread
function with the predictions of the Marx simulations?

In the "Memo regarding the PSF analysis"
(http://asc.harvard.edu/cal/Links/Acis/acis/Cal_prods/psf/psf.html)
wings measured at the XRCF are shown, but the absolute number of events at
a given angular distance from the source is not compared to Marx
predictions.

Yours,
 Henric Krawczynski
