TweedleDEE is a Tool for Determining background Emission Empirically.
Full description at arXiv.org/2408.04611
TweedleDEE creates an empirical background model for the diffuse gamma-ray emission in a 1◦ region of the sky using publicly available gamma-ray data from the Fermi-LAT. The background distribution is obtained in the form of a probability mass function (PMF), which is constructed using data off-axis from any user-specified region of interest (ROI). This background model can be used to perform a purely data-driven search for anomalous localized sources of gamma-ray emission, including new physics.
TweedleDEE produces a background PMF file for the ROI as well as a file containing the photon data from the ROI itself, both readable by the Model Agnostic Dark Halo Analysis Tool (MADHAT).
All instructions for installing and running TweedleDEE can be found on the Wiki.
