Differential Sky Spectra
Differential sky spectra for each individual spectral channel and each scan mode, prior to any destriping or combination within pixels. These spectra are the output of the calibration process described in Section 7 of the FIRAS Explanatory Supplement. The number of spectra in the dataset for each scan mode is given in Table 12.7 of the Explanatory Supplement.
