SOFIE spectral response

The relative spectral response (RSR) of a given band is a function of the intervening optical elements and the detector. Figure 1 shows the total response for each SOFIE band calculated using measured characteristics of flight components. Examples of measured detector response for various SOFIE bands are shown in Figure 2. Measured RSR plots and data are available below. The plots show measured RSR and simulated atmospheric absorption spectra. The data file header contains a format line followed by the band number, number of points, beginning wavenumber (1/cm), and wavenumber interval (1/cm). The RSR data are evenly spaced with the first point corresponding to the beginning wavennumber.
