backcorr (backcorr-3.7) [xmmsas_20211130_0941-20.0.0]



backcorr makes a background spectrum appropriate to the accumulation region used for a given source spectrum. The task calls arfgen twice; once for the source region and once for the background region. The regions are read directly from the input datasets by arfgen . This gives the integrated effective area as a function of energy over both regions. From these two effective area curves, a direct normalization of the input background spectrum is performed.
