All COBE map data are presented in a quadrilateralized spherical projection, an approximately equal-area projection (to within a few percent) in which the celestial sphere is projected onto an inscribed cube. This product specifically provides tables that relate DIRBE pixel centers to ecliptic, Galactic, and equatorial coordinates. It was provided primarily to familiarize users with the QuadSphere projection, and contains no scientific data. See the COBE documentation for a more detailed description of the QuadSphere projection and this file.
