The Likelihood Analysis of EGRET Data
Abstract
The use of likelihood for the analysis of high-energy γ-ray data from the EGRET instrument aboard the Compton Gamma-Ray Observatory is described. Maximum likelihood is used to estimate point-source flux densities, source locations, and background model parameters. The likelihood ratio test is used to determine the significance of point sources. Monte Carlo simulations have been done to confirm the validity of these techniques.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
