DECam Color Images from Co-added exposures.

I have created a set of nice, pretty color images of DECam exposures using data First Light observations and from previously known clusters targeted during SVA1. These color images are here available to the DES collaboration and can be used for PR purposes. When used, they should be credited to the Dark Energy Survey Data Management (DESDM) at NCSA.

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 very large TIFF files (~200Mb) with JPEG compresion of 15,000 x 15,000 pixels size.

DES Collaboration Logos.

Here I provide vector and bitmap images for the DES Collaboration logo to be used in presentations, poster or letter heads. They are based on the original version, and were re-generated as vector images, using the core of the RXC 2248 cluster from the First Light data as the astronomical image.
