Cosmic Background Explorer/DIRBE

Consider using the DIRBE Sky and Zodi Atlas instead. The DCAF files contain the same data as the Weekly Sky Maps but are organized differently. This product gives a pixel-by-pixel view of the intensity variations seen as a function of time, collecting all the weekly-averaged intensities measured at a given pixel into a single file. Those who wish to study or model time-variable signals, such as the zodiacal light, will find this organization convenient. There are 6 DCAF data files, one for each face of the COBE Sky Cube, and each data file is accompanied by a DCAF Pixel Index file, which is designed to facilitate data retrieval. The files are FITS binary tables. A typical DCAF data file is ~200 MB in size. To order the DCAF data on CDs, contact the Request Coordination Office. The DCAF files are on line.
