- Title:
- MAST CAOM ObsPointing ConeSearch
- Short Name:
- MAST ObsPointing

- Publisher:
- Space Telescope Science Institute Archive
- Description:
- All MAST catalog holdings are available via a ConeSearch endpoint. This service provides access to MAST holdings with pointing positional information in the Common Archive Observation Model (CAOM) database, by providing access to the ObsPointing table as a cone search. This serves the same data as the MAST CAOMTAP service, linked as an auxiliary capability. Available missions are listed at http://archive.stsci.edu/vo/mast_services.html.

- Description:
- All MAST catalog holdings are available via a ConeSearch endpoint. This service provides access to all MAST holdings with positional information that have been ingested into the Common Archive Observation Model (CAOM) and its summarized ObsCore format. It provides access to the same data as the CAOMTAP TAP service, linked as an auxiliary resource. Available missions are listed at http://archive.stsci.edu/vo/mast_services.html.

- Description:
- MAST hosts a copy of the SkyMapper DR4 catalog. SMSS DR4 contains optical photometry in the 6 SkyMapper filters (u,v,g,r,i,z) for ~700 million astrophysical sources over 26,000 sq.deg, ranging from the South Celestial Pole to Dec=+16 degrees for objects with data in all bands, and some sources as far North as +29 degrees. The photometry is drawn from over 15 billion measurements made from more than 400,000 images acquired by the 1.3m SkyMapper telescope between March 2014 and September 2021. The typical 10-sigma depths for each field range between 18.5 and 20.5 ABmag, depending on the filter, but certain sky regions include longer exposures that reach as deep as 22 ABmag. Compared to previous SkyMapper data releases, DR4 includes significant enhancements in data processing, most notably a new photometric calibration anchored to synthetic photometry from Gaia low-resolution spectroscopy, which resolves reddening- and spatial-trends identified in previous releases, especially in the bluest filters, u and v. A large number of other photometric and spectroscopic surveys have been cross-matched to the dr4.master table of objects, to facilitate various scientific investigations.
