Distributions of Fitted Values vs Input Values and estimated errors.
The true parameters are taken (or inferred) from the 3EG catalog assuming a power-law spectrum. See the description of the default parameteriztion in the Likelihood tutoial).
Binned Analysis
Counts maps for the Crab_Pulsar, the hree anticenter sources, and extragalactic diffuse tests are prepared for the following geometry:
E min = 30, E max = 3e5 MeV, 39 bins, logrithmically spaced
RA center = 83 o, eighty 0.5 o pixels
Dec center = 22 o, eighty 0.5 o pixels
A single point source: Crab_Pulsar
