The Dark Energy Survey (DES) is a ground-based optical survey that uses the wide-field DECam camera mounted on the 4m Blanco telescope to image 5000deg 2 of the southern hemisphere sky (Sanchez et al. 2010JPhCS. 259a2080S). The paper is based on 200deg 2 DES Science Verification (SV) data. This data set was taken during the 2012B observing season before the main survey (Diehl et al. 2014SPIE. 9149E.. 0VD) began.
