A file called FIRAS_TEMPERATURE_MAP_LOWF.FITS contains maps of the CMB temperature and its uncertainty, parameters of a dipole fit to the CMB temperature map (amplitude, direction, and associated uncertainties), and the average CMB temperature measured by FIRAS (2.728 +/- 0.004 K). Download the CMB temperature map.
