J/ApJ/129/475 CNOC2 Field Galaxy Redshift Survey - CNOC2 (Yee+ 2000) ====================================================================== The CNOC2 Field Galaxy Redshift Survey I. The Survey and the Catalog for the CNOC2 0223+00 Patch Yee, H.K.C., Morris, S.L., Lin, H., Carlberg, R.G., Hall, P.B., Sawicki, M., Patton, D.R., Wirth, G.D., Ellingson, E., Shepherd, C.W. =2000ApJS..131..475Y ====================================================================== Keywords: galaxies: redshifts - galaxies: photometry - galaxies: general - surveys - techniques: photometric - techniques: spectroscopic ADC_Keywords: Galaxies, Redshift Surveys ; Galaxy Catalogs ; Photometry, UBVRI ; Redshifts Description: The Canadian Network for Observational Cosmology Field Galaxy Redshift Survey (CNOC2) obtained spectroscopic redshifts for about 6200 galaxies to a nominal limit of R=21.5. The survey area of about 1.5 square degrees was spread over four patches on the sky. This catalog presents photometry and redshifts for all galaxies in the CNOC2 0223+00 Patch. A future paper will provide catalogs for the other three patches. Please read the full description of the catalog in the README file available at the website below.

The astrometry is accurate to about +-1 arcseconds RMS. Objects should be named using the prefix CNOC2 followed by the standard IAU coordinate designation for coordinates with this accuracy. For example, an object at the center of the coordinate system would be known as CNOC2 022329.9+000512. ---------------------------------------------------------------------- History: 01-Aug-2000 : Version 1 of cnoc0223.dat 13-Feb-2001 : Version 2 of cnoc0223.dat (corrected some photometry) ---------------------------------------------------------------------- Author's address: Howard Yee ====================================================================== (End) Pat Hall [Univ.
