Hubble Source Catalog (V1 and V2)

Listed in IVOA Registry (Virtual Observatory)

The Hubble Source Catalog is designed to help optimize science from the Hubble Space Telescope (HST) by combining the tens of thousands of visit-based source lists in the Hubble Legacy Archive (HLA) into a single master catalog.

Description

Version 1 of the Hubble Source Catalog includes WFPC2, ACS/WFC, WFC3/UVIS, and WFC3/IR photometric data generated using SExtractor software to produce the individual source lists. The catalog includes roughly 80 million detections of 30 million objects involving 112 different detector/filter combinations, and about 160,000 HST exposures.

Source lists from Data Release 8 of the HLA are matched using an algorithm developed by Budavari & Lubow (2012ApJ...761..188B). The mean photometric accuracy for the catalog as a whole is better than 0.10mag, with relative accuracy as good as 0.02mag in certain circumstances (e.g., bright isolated stars). The relative astrometric residuals are typically within 10mas, with a value for the mode (i.e., most common value) of 2.3mas.

The absolute astrometric accuracy is better than 0.1" for most sources, but can be much larger for a fraction of fields that could not be matched to the PanSTARRS, SDSS, or 2MASS reference systems. In this paper we describe the database design with emphasis on those aspects that enable the users to fully exploit the catalog while avoiding common misunderstandings and potential pitfalls. We provide usage examples to illustrate some of the science capabilities and data quality characteristics, and briefly discuss plans for future improvements to the Hubble Source Catalog.
