Optical mosaics in u′, g′, and r′ bands of seven Abell galaxy clusters were taken by Dark Energy Camera (DECam) from April 10th to 11th in 2013 (Proposal ID: 2013A-0612, PI: Y. Sheen) and August 19th to 22nd in 2014 (Proposal ID: 2014B-0608, PI: Y. Jaffé). DECam is mounted at the prime focus of the Blanco 4-m Telescope at Cerro Tololo Inter-American Observatory (CTIO). DECam features a ∼3 deg2 field of view (FoV) consist- ing of sixty-two 2k × 4k pixel CCDs, with a total of 520 million pixels for each FITS mosaic.
We make use of pipeline-reduced science, weight, and data quality map (DQM) FITS image data of the clusters for both single-exposure and combined mosaics from NOIRLab Astro Data Archive2. Basic information for the clusters and their FITS mosaics is summarized in Table 1 of Kim et al. (in prep). The multiple standard-star fields are also ob- served each observing night and used for the flux calibra- tion. Each field was observed at least twice with enough time intervals to measure the atmospheric extinctions at different airmasses
Example images of the DECam data are on the bottom.
