All data are validated by the NStED science staff and traced to their sources. NStED is the U.S. data portal for the CoRoT mission. As of June 2007, the database catalogued 140,230 stars, [1] but by December 2011, SDtED was no longer in operation. Most data and services have been transferred to the NASA Exoplanet Archive.

The Guide Star Catalog is an online catalogue of stars produced for the purpose of accurately positioning and identifying stars satisfactory for use as guide stars by the Hubble Space Telescope program. The first version of the catalogue was produced in the late 1980s by digitizing photographic plates and contained about 20 million stars, out ...
A significant expansion of the catalog, Guide Star Catalog II, was published in 2008. The Guide Star Catalog II (GSC-II) was compiled by the Catalog and Surveys branch of the Space Telescope Science Institute and the astrometry team of the Astronomical Observatory of Torino (Italy). It has entries for 945,592,683 stars, and has positions ...
ESO Science Archive has been providing access to data from astronomical catalogues since 1988. [1]An astronomical catalogue is a list or tabulation of astronomical objects, typically grouped together because they share a common type, morphology, origin, means of detection, or method of discovery.
Some objects originally thought to be deep sky objects and listed in the NGC have been subsequently shown to be ordinary stars, so their inclusion in the catalog is now considered erroneous. [1] This list of stars is based on the "NGC 2000.0" version of the catalog, which lists the stars in its errata, [ 1 ] supplemented with data on each ...
In contrast to the PPM, these older catalogs are based on (1) the now obsolete FK4 system of positions and proper motions, and (2) only two position measures per star. [2] While the SAO catalog is more or less complete to V=9, with 4,503 stars fainter than V=10, the PPM catalog is fairly complete to V=9.5, with 102,672 stars fainter than V=10 ...
