Carlsberg Meridian Catalogue 12

Note that CMC12 has been superceded by CMC13.

Carlsberg Meridian Catalogue 12 was released on 3 July 2002. This is an astrometric and photometric catalogue of 6.3 million stars in the red (SDSS r') magnitude range 9 to 17. This catalogue is the initial release of the CMT CCD survey and covers the declination range -3° to +3°. The data for the remainder of the survey (+3° to +30°) has been observed and reduced and is in the process of being calibrated.
