CXBTools

CXBTools is a small toolbox to deal with (unresolved) point sources from the Cosmic X-ray Background (CXB) in Astrophysical soft X-ray spectra. The tools are written to help to determine the contribution from unresolved X-ray sources to the background spectrum in X-ray spectra. They were especially written for the EPIC instruments aboard XMM-Newton and for the analysis of extended sources. The package contains two tools to estimate the unresolved flux from point sources and one tool to determine the optimal extraction region and flux cut for point sources within a certain extraction annulus. This is the first release version of this toolbox.
