Notes. Multiplicative factors to apply to correct values for galaxies with spectral energy distributions well represented by a modified black body with a grain emissivity parameter β and a temperature T in the given ranges. Color corrections for β = 2 and T = 15,20,25 K, are consistent with those given in Davies et al. (2012); in that paper, however, the K4 correction is included in the color correction for extended sources, while here it is included in the fluxes.
