Wilkinson Microwave Anisotropy Probe
Bandpass Frequency Response
The frequency response of the two detectors in each of WMAP's twenty radiometers (two per differencing assembly) are provided in this dataset; there is one file per radiometer. Each file contains three columns:
In principal the bandpass data for the two detectors should be weighted by their response to a thermal spectrum corresponding to how the WMAP data is calibrated in flight. In practice, weighting this bandpass data based upon the area beneath each response curve should be sufficient. It is worth noting that the center frequencies have drifted over time (Bennett et al. 2013); the effective frequency calculator on the software page and the corresponding IDL procedures in the delivered IDL library apply a correction factor to account for this drift over the nine-year mission.
These are the same files released in the fourth WMAP data release.
