Table of extracted sources with calibrated magnitudes (applause_dr2.source_calib)
The table has 2592531200 rows, 68 columns.
Description
Sources with calibrated magnitudes by pyplate. For calibration a crossmatch of UCAC4 and APASS was used. Catalog identifiers are given, together with match quality indicators, when a match in those cataclogs has been indentified. The magnitude calibration uses the values of the phot_* tables. Unique Identifier source_id
