allsky-point-source-detection

This repo provides code for detecting point sources on a sphere (i.e., the sky) by applying the continuous wavelet transform on raw count data. We use this tool to detect faint gamma-ray point sources from Fermi-LAT. See my skysearch repo for a pipeline. We use the technique originally proposed by arXiv:0212578.
