The Blanco DECam Bulge Survey (BDBS) is an LSST precursor program to image ~200 sq. deg. of the Galactic bulge from -10 < l < +10 to -10 < b <-2. BDBS targets the relatively low extinction regions of the Southern Galactic bulge. The Survey is in ugrizY, obtained with DECam, with the goal of retaining precise photometric calibration even at the bright end.

The Blanco DECam Bulge Survey (BDBS) portal is a project of Indiana University's Pervasive Technology Institute funded in part by the National Science Foundation.
