Status of the BATSE enhanced earth occulation analysis package for studying point sources

The Compton Gamma‐Ray Observatory’s Burst and Transient Source Experiment (BATSE) has a powerful capability to provide nearly uninterrupted monitoring in the 25 keV–2 MeV range of cosmic point sources using occultation by the Earth. The physical model for the background variations, central to this package, will allow use of more data, enhancing the sensitivity by a factor of several compared to the BATSE Mission Operations package, which has proven valuable. This physically‐based model fits for the diffuse background (including Earth blockage), prompt cosmic‐ray effects, South Atlantic Anomaly activation, atmospheric cosmic‐ray secondaries, and cosmic sources in 14 Medium Energy Resolution energy bands on the Large Area Detectors. Features include the ability to correlate set and rise of a given source and to handle multiple sources within the fit window. The count spectrum is deconvolved using the detector energy response matrix to yield a source photon spectrum. We describe the current status and perfor...
