The Hubble Source Catalog (HSC) is designed to enhance the science obtained from the Hubble Space Telescope by combining the tens of thousands of visit-based source lists in the Hubble Legacy Archive (HLA) across filters and detectors into a single master catalog. The catalog contains data from the major Hubble imaging instruments: Wide Field Planetary Camera 2 (WFPC2), Advanced Camera for Surveys (ACS), and Wide Field Camera 3 (WFC3). It is based on cross matching and astrometry algorithms developed by Budavari & Lubow (2012). We recently released Version 2 that is three times the size of Version 1 and includes some new features. The catalog can be accessed through a variety of interfaces (see http://archive.stsci.edu/hst/hsc/). The HSC provides descriptions of astronomical objects involving multiple wavelengths and epochs. High relative positional accuracy of objects is achieved across the Hubble images, often with sub-pixel precision of a few milliarcseconds.
