Mining the Entire GALEX Data Set for Sub-Visit Variability
Abstract
We have implemented a new calibration pipeline for GALEX direct imaging data that permits the extraction of sub-visit precision light curves from full-frame images. The software is currently being used on Amazon Web Services (AWS) to recalibrate the entire GALEX direct imaging data corpus at 120 seconds of depth, approximately equivalent to the GALEX All-Sky Survey (AIS) mode data, and the resulting catalog is being mined for examples of fast astrophysical variability. We present comparative photometry between this new pipeline and the gPhoton tools and archive of GALEX photon events as well as initial results from the variability search.
