Beginning of ReadMe : I/282 The CMT CCD Drift Scan Survey (Evans+, 2002) ================================================================================ The Carlsberg Meridian Telescope CCD Drift Scan Survey Evans D.W., Irwin M.J., Helmer L. <Astron. Astrophys. 395, 347 (2002)> =2002A&A...395..347E ================================================================================ ADC_Keywords: Positional data ; Meridian observations ; Surveys Keywords: astrometry - methods: data analysis - techniques: image processing - techniques: photometric - catalogues - surveys Description: This is CMC12 (Version 1.0), an astrometric and photometric catalogue of 6.3 million stars in the red magnitude range 9 to 17. The Carlsberg Meridian Telescope (CMT) underwent a major upgrade in March 1999. A 2k by 2k CCD camera was installed with a Sloan r' filter operating in a drift scan mode. With the new system, the magnitude limit is r'_CMT_=17 and the positional accuracy is about 0.035". The main task of the CMT is to map the sky in the declination range -3deg to +30deg with the aim of providing an astrometric, and photometric, catalogue that can accurately transfer the Hipparcos/Tycho reference frame to Schmidt plates. The current release (Version 1.0) comprises all the observations made between March 1999 and March 2002 with the new CCD in the declination band -3deg to +3deg. It is intended to release the rest of the catalogue later.
