Color Images

One color image per selected survey will be produced if resampling has also been selected. The SDSS color image uses g, r, i bands; the DSS color images uses dss2b, dss2r, dss2ir (only when all three are available); and the 2MASS color image uses J, H, Ks. Resampling is needed so that all three images have the same projection center, pixel size, and orientation.
