  HSTCosmicrays is a python-based pipeline designed to find and characterize
cosmic rays found in dark frames (exposures taken with the shutter closed).
Dark exposures are obtained routinely by all the Hubble Space Telescope (HST)
instruments for calibration. The main processing pipeline runs locally or in
the cloud on AWS. To date, we have characterized more than 1.2 billion cosmic
rays in ~76,000 dark frames obtained with CCDs from the four active instruments
ACS/HRC, ACS/WFC, STIS, WFC3/UVIS, and the legacy instrument WFPC2.
