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
mos-spectra.
The resultant image is in detector coordinates which is then
transformed into sky coordinates by the perl script
rot-im-det-sky.
mos_back 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.
