Mariner 9 infrared interferometer spectrometer (IRIS) reduced data records documentation

The Mariner 9 spacecraft was successfully inserted into orbit around Mars. One of the five instruments on board, an infrared interferometer spectrometer is used to record the thermal emission spectrum of Mars between 200 and 2000 cm/1. The spatial resolution for vertical viewing is a circular area of approximately 110 km diameter for a periapsis height of 1400 km. The total number of calibrated spectra included in the final data set is 21167. The final calibrated thermal emission spectra contained in the reduced data records are reported.
