Additionally, access to Hubble Legacy Archive data and the Hubble Source Catalog. About 30% of the ACS/WFC, WFC3, and WFPC2 images are not included in the catalog due to image quality and other issues If you have questions, or items to This is a description of the current version of the Hubble Source Refereed publications making use of the HSC should therefore include this footnote in the acknowledgements: Authors are also asked to acknowledge the "Hubble Source Catalog" in the text of the paper, and consider a reference to the Budavari & Lubow (2012), The mean photometric accuracy for the catalog as a whole is better than 0.10 mag, with relative More detailed information can be found on the Frequently Asked The Hubble Source Catalog is a database from which astronomers can obtain the Hubble measurements of specific astronomical objects they want to investigate. Catalog Tables and Additional Information ¶. About 19% of the sources could not be cross-matched with sources in other visits. For additional information on the catalogs please visit the HSC Data Archive Home Page. The Hubble Source Catalog (HSC) is designed to facilitate science from the Hubble Space Telescope by combining 48,000 visit-based source lists from the Hubble Legacy Archive (HLA) into a single master catalog. out. The Hubble Catalog of Variables is the first, homogeneous catalog of variable sources created from the highly diverse, archival Hubble data, and is the deepest catalog … visit-based source lists in the After correction, the 4. The default is to use mag_aper2 Source Extractor values for 2. You can request NumImages > 1 (or more) to filter out many artifacts. Sky coverage can be very non-uniform (unlike surveys such as SDSS) due to the highly variable HST observing patterns. We have also visually identified the U-band sources within a Hubble ACS/B-band image of the GOODS-S field that overlaps the UDF. HSC Data Use Policy: You can access the EHST Archive to search for and retrieve all public data observed by HST since its launch to today: Hubble Legacy Archive (HLA) To celebrate the 30th anniversary of the Hubble Space Telescope's launch, NASA has released new Hubble images of 30 of the Caldwell catalog space sights to see. source lists from HLA version DR10 (data release 10). There are also videos available. Several Use Cases are available to give you step by step instructions. This is more robust and less sensitive to outliers than the RMS used in The catalog is based on observations taken on more than 6000 visits (telescope pointings) of ACS/WFC and more than 25000 visits of WFPC2. WFPC2, ACS/WFC, WFC3/UVIS and WFC3/IR astrometric residuals of cross-matched sources are significantly Whitmore et al. The HSC is based on data from the Hubble Legacy Archive (HLA). Cross-matching between HSC sources and spectroscopic COS, STIS, FOS, and GHRS observations. We have created an initial catalog of objects observed by the WFPC2 and ACS instruments on the Hubble Space Telescope (HST). The scatter in magnitudes is measured using the median absolute deviation (MAD) of the differences (2016) paper describing the HSC. The catalog is obtained by cross matching by position in the sky all Hubble Legacy Archive (HLA) Source Extractor source … We apologize for the inconvenience. bring to our attention, please send them to: archive help. 2016) has recently provided photometric measurements of all sources detected from a homogeneous reduction and analysis of archival images from the HST, thereby enabling such a vari- ability search.
