![]() ![]() The crossmatching algorithms and the properties of the initial (Beta 0.1) catalog are described in Budavari and Lubow (2012). This reduces the area of a plate over which a plate model needs to accurately represent the relationship between measured coordinates and ideal coordinates. ![]() Each plate is (artificially) divided into subplates which then can be overlapped. Research Staff Positions at STScI- General Astronomy & Planetary Science 0005678. In addition, the catalog includes source nondetections. An expansion of the plate-overlap method of astrometric data reduction to a single plate is proposed. The relative astrometry is supported by using Pan-STARRS, SDSS, and 2MASS as the astrometric backbone for initial corrections. After correction, the astrometric residuals of crossmatched sources are significantly reduced, to typically less than 10 mas. Also uses os.path.expanduser to replace symbols. ![]() The crossmatching process involves adjusting the relative astrometry of overlapping images so as to minimize positional offsets between closely aligned sources in different images.

The HSC v2 contains members of the WFPC2, ACS/WFC, WFC3/UVIS and WFC3/IR Source Extractor source lists from HLA version DR9.1 (data release 9.1). While the misfigure of the HST primary mirror has not rendered astrometry impossible. This service uses an older version of the Hubble Source Catalog. #Stsci astrometry archiveThe Hubble Source Catalog (HSC) is designed to optimize science from the Hubble Space Telescope by combining the tens of thousands of visit-based source lists in the Hubble Legacy Archive (HLA) into a single master catalog. The MAST Archive at STScI TAP end point for the Hubble Source Catalog, version 2.1. ![]()
