Program Purpose

The KBURST program is to be used as a tool to look for time variation in a particular source or pointing direction. It is capable of searching a specified time range, a full viewing period or multiple viewing periods. Three statistical tests are then applied to the data. No modeling of the gamma-ray background is performed. The tests are performed on all incident gamma-rays from the pointing direction that meet the specified earth zenith constraint. Three plots are produced for analysis. The first shows intensity at the specified direction as a function a time and a chi-squared test to the data for variability. The second plot shows cumulative counts versus time and Kolmogorov-Smirnov test for time variability. This plot displays both expected and measured counts. The third plot is a statistical likelyhood analysis of which orbit is the most unlikely orbit based on the expected counts.
