Color Correction Tables
Following the IRAS convention, DIRBE flux densities are derived assuming a nu*I(nu) = constant source spectrum. Color corrections must be applied to the quoted flux densities to derive true flux densities when the spectrum differs in shape from that assumed. The set of Color Correction Tables given in Appendix B of the DIRBE Explanatory Supplement take into account the system spectral response and pertain to a variety of source spectra (power laws and modified Planck functions). The same data are provided in an ASCII table.
