pointsrc

Abstract:

Calculates the xspec normalization per square arcminute for the Cosmic X-ray background after removal of point sources to some limiting level (min_flux). ELF is shorthand for the logN-logS. This task was originally a subtask of the SAS esas task named point_source prior to SAS-21 and retains all of its functionality.
