This package contains python code for computing aperture photometry for
unresolved sources in astronomical x-ray images, as described in the article
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
