Description

This file contains the glitchrate correction slopes and intercepts for the FIRAS data. These corrections were computed for each channel and scan mode by a linear lease squares fit to the average variance and glitch rate of each calibrated sky spectrum. The average variance for a spectrum is defined to be: ((Nifgs * Real_Var) / D-Vector^2) / Nfreq. These corrections are used in the following manner: Nifgs' = Nifgs / (Intercept + Slope * Glitchrate).

The spectra used in these computations were calibrated with the F16_93HYBRID calibration model solutions. For each row above, entries are in the order short slow, short fast, and long fast.
