South Galactic Cap u-band Sky Survey (SCUSS): Data Reduction


The South Galactic Cap u-band Sky Survey (SCUSS) is a deep u-band imaging survey in the Southern GalacticCap, using the 90Prime wide-field imager on the 2.3 Bok telescope at Kitt Peak. The survey observations started in2010 and ended in 2013. The final survey area is about 5000 deg2 with a median 5σ point source limitingmagnitude of ?23.2. This paper describes the survey data reduction process, which includes basic imagingprocessing, astrometric and photometric calibrations, image stacking, and photometric measurements. Surveyphotometry is performed on objects detected both on SCUSS u-band images and in the SDSS database. Automatic,aperture, point-spread function (PSF), and model magnitudes are measured on stacked images. Co-added aperture,PSF, and model magnitudes are derived from measurements on single-epoch images. We also present comparisonsof the SCUSS photometric ca
