BatAnalysis - A Comprehensive Python Pipeline for Swift BAT Data Analysis

The Swift Burst Alert Telescope (BAT) is a coded aperture gamma-ray instrument with a large field of view that primarily operates in survey mode when it is not triggering on transient events. Survey data comprises > 90% of all of BAT data by volume and allows for the tracking of long term light curves and spectral properties of cataloged and uncataloged hard X-ray sources between 14 and 195 keV. Until now, the survey dataset has not been used to its full potential due to the complexity associated with its analysis and the lack of easily usable pipelines. Here, we introduce the BatAnalysis python package which provides a modern, open-source pipeline to process and analyze BAT survey data. BatAnalysis allows members of the community to use BAT survey data in more advanced analyses of astrophysical sources. Additionally, the package now allows for the convenient analysis of BAT event data, unlocking the full potential to produce spectra and light curves with arbitrary time bin and energy bins. The BatAnalysis package allows for ~19 years of BAT survey and event data to be used in a systematic way to study a large variety of astrophysical sources.
