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 mosspectra. The resultant image is in detector coordinates. The resultant image is in detector coordinates which is transformed into sky coordinates by the sas task rotdet2sky. mosback creates several QDP plot files which shows the source and model background spectra for the observation and other diagnostics. 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.
Warning and requirements: mosback is part of the esas package integrated into SAS, but it is limited to work within the esas data reduction scheme. This is specially true wrt the structure and names of the input files. In particular, mosback assumes that another task from the package, mosspectra has been successfully run for the exposures to be used.
