Abstract
We compare the independent FIRAS and DIRBE observations from COBE in the wavelength range of 100-300 μm. This cross calibration provides checks of both data sets. The results show that the data sets are consistent within the estimated gain and offset uncertainties of the two instruments. They show the possibility of improving the gain and offset determination of DIRBE at 140 and 240 μm.Keywords
