Table information for 'applause.main'


Table Description: A redux of the calibrated subset of APPLAUSE to the obscore schema, with constant columns removed.

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

Resource Description: APPLAUSE DR3 contains images and metadata from 24 plate collections in Hamburg, Bamberg, Potsdam, Tautenburg and Tartu, a total of 101138 scans of 70276 photographic plates. The present table contains metadata records for singly exposed plates with astrometric solutions in APPLAUSE (about 44000). It is mainly intended as a basis for publishing suitable APPLAUSE plates in the Obscore schema through the TAP service in GAVO's Heidelberg Data Center. A TAP service with more complete metadata and, in particular, extracted sources, is available at
