1. BEHR: Bayesian Estimation of Hardness Ratios
... BEHR is a standalone command-line C program designed to quickly estimate the hardness ratios and their uncertainties for astrophysical sources. It is especially useful in the Poisson regime of low counts, and computes the proper uncertainty regardless of whether the source is detected in both passbands or not. ... src are the counts within the source region, and *bkg are counts within the background region. ... soft-band counts in source region . hard-band counts in source region . ...
