Statistical Reliability of GammaRay Line Observations
Abstract
A procedure for evaluating the statistical significance and the confidence levels of a positive source and of line observations in gammaray astronomy is presented. The formulas derived make use of maximum likelihood ratio testing. The method is applied to a number of measurements of gammaray lines from Crab Nebula, Galactic center, Galactic plane, solar flare, and transient events, and several statistically reliable measurements are thereby distinguished.
