APPLAUSE Data Release 2 (applause_dr2)


The APPLAUSE Data Release 2 contains metadata about photographic plates and data extracted from digitized plates.

The source catalogue contains 2.59 billion extracted sources. The majority of sources have their positions (right ascension and declination) calibrated with the help of the Tycho-2 and UCAC4 catalogues. The database contains 1.407 billion sources with matched UCAC4 designations and 182 million sources with Tycho-2 designations.

The APPLAUSE DR2 database is organised in 16 tables.

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