bogopix results for two HFI detectors, compared with those from the solar dipole calibration. Gain values for individual rings have been smoothed with a width of 50 rings (about 2 days), to increase the signal-to-noise ratio. There is good agreement of the relative gain variations between the bogopix results and those obtained from the HFI maps, except for the time intervals where the solar dipole amplitude is lower than the Galactic emission. The averaged value of the gains are, however, offset by factors (different from one detector to the other) of the order of 0.5 to 1%.
