Product Name
Solar Elongation = 90 deg Sky Maps
Mission
COBE/DIRBE

Description

These maps provide an estimate of the infrared intensity at each pixel and wavelength band based on an interpolation of the observations made at various times at solar elongations close to 90 degrees. To first order, this product depicts the sky as if it were observed through a temporally constant IPD foreground, thus enabling straightforward modeling and subtraction of the zodiacal light to a level adequate for many Galactic studies, the obvious drawback being that only a small portion of the available DIRBE data is represented. The Solar Elongation = 90 deg Sky Maps (1 FITS file per wavelength band, each 12.9 MB), are network-accessible and will later be provided on CD-ROM.
