The color images of DECam exposures were created using STIFF (version 2.1.3) from co-added fits files using SWArp using a pixel-scale of 0.5 arcsec/pixel. I used images that were processes through the initial steps of the DESDM pipeline (crosstalk, bias, flats, astro-alignment) and were futher cleaned of spurius objects using mkbleed to mask and interpolate over saturated stars and bleed trails (with interpolation on) and immask (version0.2.1) to mask and detect satellite trails and cosmic rays. The color images, are tiff files with jpeg compresion of 15,000 x 15,000 pixels size.
