Differential Calibration Spectra
The time-ordered differential calibration spectra for each individual spectral channel and each scan mode. These spectra are the output of the calibration process described in Section 7 of the FIRAS Explanatory Supplement, applied to the calibration coadded interferograms that are used to compute the calibration model. As described in section 11.2 of the Explanatory Supplement, these spectra are binned by temperature plateaus. The number of spectra in the dataset for each scan mode is given in Table 12.8 of the Explanatory Supplement.
