pnback

Abstract:

This task creates model particle background spectra and images (if selected with a non-zero energy range) for the selected region from the intermediate files produced from pnspectra. The resultant image is in detector coordinates which is then transformed into sky coordinates by the SAS task rotdet2sky. pnback creates a QDP plot file which shows the source and model background spectra for the observation. Any enhancement of the data over the particle background model at higher energies probably indicates residual soft proton contamination, unless there are really hard and bright sources in the field. This task was originally a subtask of the SAS esas task named pn_back prior to SAS-21 and retains all of its functionality.
