Abstract:
The Red-Sequence Cluster Survey (RCS) is a ∼100°2, two-filter
imaging survey in the RC and z' filters, designed primarily to locate
and characterize galaxy clusters to redshifts as high as z=1.4. This
paper provides a detailed description of the survey strategy and
execution, including a thorough discussion of the photometric and
astrometric calibration of the survey data. These catalogs,
representing about 10% of the total survey and comprising a total of
429 candidate clusters and groups, contain a total of 67 cluster
candidates at a photometric redshift of 0.9<z<1.4, down to the chosen
significance threshold of 3.29σ.
