MIT/Amsterdam M 31 Survey
Listed in NASA Data Portal
The MIT/Amsterdam M 31 Survey, or the Extended Magnier et al. Catalog of Objects in the Field of M 31, is based on deep BVRI CCD photometry that was performed on a 1 square degree region of M 31.
Description
The observations were made between September 12 and September 27 1990, using the McGraw-Hill 1.3m telescope at the Michigan-Dartmouth-MIT (MDM) observatory at Kitt Peak. The catalogue has typical completeness limits of 20.7 (Bmag), 21.7 (Vmag), 20.2 (Rmag) and 20.5 (Imag), although there is a large region in the inner disk for which the completeness limits are substantially deeper: 22.3 (Bmag), 22.2 (Vmag), 22.2 (Rmag), and 20.9 (Imag).
The photometric accuracy is about 2% at Vmag = 19. The final astrometric calibrations take into account the systematic error discovered in the Berkhuijsen et al. (1988, A&AS, 76, 65) catalog by Magnier et al. (1993, A&A, 272, 695). They are in the J2000 system and are eventually tied to the HST Guide Star Catalog.

The final photometric calibrations are tied via the NGC 206 region to photometry taken at the Michigan-Dartmouth-MIT (MDM) 1.3m in September and October 1993. These are tied to the Landolt (1992, AJ, 104, 340) system of standard stars, and are in the Johnson-Kron-Cousins system (BVRcIc). This version of the MIT/Amsterdam M31 Survey Catalog was created at the HEASARC in March 1999 based on the CDS/ADC Catalogue II/208.
The HEASARC revised this version in February 2001. This is a service provided by NASA HEASARC .
