INFRARED INTERFEROMETER SPECTROMETER (IRIS)
    Nov 14, 1971 (Ls 292.3 MY 9) to Oct 18, 1972 (Ls 98.1 MY 10)

























    The spatial and temporal distributions of the infrared spectra obtained with the Mariner 9 IRIS instrument during that orbiting missions' lifetime spanning Ls 293 (MY 9) through Ls 98 (MY 10).











    The Data contained within the Mariner 9 IRIS PDS archive are provided in the form of spectral intensity measurements (W cm-2 cm-1 sr-1). The data span the wavenumber range from 199.72 cm-1 to 1960.675 cm-1 and the spectral resolution is 1.174753507 cm-1 at 1500 cm-1.
