Information on Service 'Potsdam Carte du Ciel Plates'

[Use this service from your browser]

Further access options are discussed below

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.

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
