COBE DIRBE ProductsAnnual Average MapsDownload Links:
These maps provide a single, mission-averaged intensity value per pixel for each of the 10 DIRBE bands. The effect of coaddition is to improve sensitivity to faint emission. Since these maps average over the variable zodiacal light signal, they are useful primarily at wavelengths at which the IPD signature is weak, especially 140 and 240 microns. The Annual Average Maps also provide information on the depth of sky coverage over the whole cryogenic mission. These maps (1 FITS file per wavelength band, each 10.6 MB) are network-accessible and will later be provided on CD-ROM. |
