The CNOC2 survey consists of 4 patches , each laid out in the rough L shape shown above. Each patch consists of 17-19 overlapping fields , each field being the size of a single MOS pointing. The following table summarizes the main properties of the 4 patches. Coordinates are the 1950.0 centers of the a0 fields. Number of redshift values are taken from the V1.5 catalogs, which are not the final versions.
Area is in square arc minutes.
Data and catalogs will be made available several ways. Currently the full catalog is only available for the 0223 patch. Interactive image cutouts and partial catalog data. The raw images can be obtained from the CFHT Archive.
