Table information for 'potsdam.plates'

General

Table Description: Potsdam plate scans with astrometry.net calibration.

This table is available for ADQL queries and through the TAP endpoint.

Resource Description:

Publication of scans of photographic plates from the so-called "Potsdam zone" of the Carte du Ciel project (32 deg to 39 deg). A total of 977 plates of 2 square degree sky regions was observed and recorded between 1913 to 1924. Since Potsdam Observatory ended participation in the Carte du Ciel project, these observations were so far not analysed or published. Plates were scanned in by a flat bed scanner in 2007-2008. Limitations in astrometric precision are therefore to be expected, and specific observational restrains apply, such as multiple exposures on certain plates.
