APPLAUSE DR3 (applause_dr3)


The APPLAUSE Data Release 3 contains metadata about photographic plates and data extracted from digitized plates.

The source catalogue contains 3.508 billion extracted sources. The majority of sources have their positions (right ascension and declination) calibrated with the help of the Tycho-2 and a crossmatch of (updated) UCAC4 and APASS catalogues. The database contains 2.065 billion sources with matched UCAC4 designations, 1.179 billion apass matches and 367 million sources with Tycho-2 designations.

The APPLAUSE DR3 database is organised in 18 tables.

Along with the data we publish the version of the pyplate software which was used to process the scanned material.
