The following analysis of Cassiopeia A was done using pointlike with a 15 degree ROI and a LogParabola fit. The energy range used in the analysis is 100MeV to 100GeV, although the SEDs are shown only in the range of 1-100GeV since there is no reliable measure of their flux at lower energies.

The galactic diffuse model used: ring_2year_P76_v0.fits
The isotropic diffuse models used: isotrop_2year_P76_source_v0.txt (For front and back events), isotrop_2year_P76_source_v0_front.txt (For front only events), isotrop_2year_P76_source_v0_back.txt (For back only events)
Catalog used: gll_psc_v04.fit
