README

This package contains python code for computing aperture photometry for
unresolved sources in astronomical x-ray images, as described in the article
"DETERMINING X-RAY SOURCE INTENSITY AND CONFIDENCE BOUNDS IN CROWDED FIELDS",
Primini, F.A and Kashyap, V.L. 2014, The Astrophysical Journal, v. 796, pp. 24-37.

The code is designed to run within the CIAO data analysis environment
(http://cxc.cfa.harvard.edu/ciao).


xap.py						       Main Python program
xap_funs.py					       Function and Class definitions for xap.py
xap.par						       CIAO style parameter file for xap.py
