| 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. | ||
|
|
||
| This version of the code uses the CIAO Sherpa and pyBLoCXS environments to sample | ||
| the posterior probability distribution. | ||
|
|
||
| The code is designed to run within the CIAO data analysis environment | ||
| (http://cxc.cfa.harvard.edu/ciao), but has not yet been tested with CIAO v. 4.10 | ||
| or Python 3. | ||
