Point Source Detection with Low Count Rates and Nonuniform Background (2007)

Abstract
). ffl For transient detection, there is a premium on fast algorithms. ffl Systematic anomalies -- Effective Exposure expensive to compute a priori -- Background is nonuniform: edges, pinholes, "racetracks", etc. -- Attitude solution still has kinks ffl Keep a human in the loop -- Look beyond the p-value: residual maps, light curves, etc. -- Opportunities for "selection effects" abound Astrophysics and Radiation Measurements Group Los Alamos National Laboratory Point Source Detection. . . Uniform Background Methods background annulus point source candidate ffl Background is estimated from an annular region surrounding the potential source region. ffl S counts in an inner box of area A src . B counts in outer annulus of area<F72
