Coadded Sky Interferograms

Download Links:

Pixel-ordered coadded sky interferograms for each individual spectral channel and scan mode. As described in sections 11.2 and 11.3 of the FIRAS Explanatory Supplement, the raw sky interferograms have been sorted by pixel number and ICAL temperature setting, normalized to unit MTM sweep and unit gain, and averaged together.
