South Pole Telescope
Spectral Bandpass Functions for the 2008 Season
These files contain average spectral bandpass functions for South Pole Telescope (SPT) observations during the 2008 season in the 150 GHz and 220 GHz bands, produced for the first SPT data release in December 2011.
The spectral bandpass functions were estimated by averaging together measurements made using a beam-filling Fourier Transform Spectrometer for approximately 50% of the detectors in each band. These functions represent the instrument response to a flat-spectrum source. They are presented as peak-normalized response functions tabulated as a function of frequency in GHz.
A complete description of the observations, data processing, calibration, instrument response, and mapmaking process for this data release is in Schaffer et al. 2011, ApJ, 743, 90.
