The calculation of offaxis radiance for a sensor involves two programs, LOWFILT and OAREJ, and a set of data files specifying the sensor spectral response, sensor offaxis rejection response, and the radiance profile for the earth limb. For this description, the earth limb profile is provided as data generated by the LOWTRAN4 program, although more recent or alternative limb profile data could be used, provided the data format is preserved. For this study, a series of models of offaxis response functions has been developed to characterize the performance of several infrared sensors, including the Zodiacal Infrared Project (ZIP) telescopes, which were used for both the ZIP and Earth Limb Clutter (ELC) missions, and the SPIRE telescope. A number of observational and theoretical considerations were incorporated into the development of these models, and comparisons of the computed offaxis in-band radiance to actual flight data have been performed. Further investigations are still in progress.
