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.
