Abstract
The Blanco Cosmology Survey (BCS) is a 60 night imaging survey of ~80 deg2 of the southern sky located in two fields: (_s13_s17945_s19, _s13_s17948_s19) = (5 hr, -55°) and (23 hr, -55°). The survey was carried out between 2005 and 2008 in griz bands with the Mosaic2 imager on the Blanco 4 m telescope. The primary aim of the BCS survey is to provide the data required to optically confirm and measure photometric redshifts for Sunyaev-Zel_s14dovich effect selected galaxy clusters from the South Pole Telescope and the Atacama Cosmology Telescope.
