Model Errors

Calibration model parameters are given in the 10 Calibration Model Solution files. Errors associated with the calibration model are given in the 16 Calibration Error Terms files. The four Model Errors files give estimates of the possible systematic errors caused by the choice of destriper model functions at low spectral resolution. The file designated "LOWF," pertains to low-frequency (30 - 660 GHz) data. The other three files ("HIF2,","HIF3,","HIF4,") are subsets of the high frequency data processed with separate destriper model functions (see the table below for frequency ranges). For a full discussion, see the FIRAS Explanatory Supplement (especially subsections 5.6 ). FITS headers are listed in the FIRAS Explanatory Supplement Appendix G.
