This page summarizes analysis results obtained using GammaLib on the Crab.
The interface has been validated using the COMPTEL data from Viewing Period 1. This observation was a 14 days pointing on the Crab. The analysis has been performed using GammaLib-00-07-00. The background has been modeled using a Phibar-fitted DRG file. This is only a crude background model, which may explain the discrepancy between nominal and fitted fluxes. The quoted sensitivities and the sensitivity derived by multiplying the statistical uncertainty by a factor of 3 are pretty close. Units are ph/cm2/s.
Energy | Nominal flux (1) | Fitted flux | Error | Quoted sensitivity (2) | Sensitivity (3*error) |
0.7-1 MeV | 5.55e-4 | 8.55e-4 | 5.80e-5 | 2.01e-4 | 1.74e-4 |
1-3 MeV | 1.07e-3 | 1.283e-3 | 5.633e-5 | 1.68e-4 | 1.69e-4 |
3-10 MeV | 3.98e-4 | 2.42e-4 | 2.48e-5 | 7.3e-5 | 7.43e-4 |
10-30 MeV | 1.06e-4 | 5.03e-5 | 8.28e-6 | 2.8e-5 | 2.48e-5 |
