DESCRIPTION Mars Odyssey GRS SGS (Summed Gamma Spectra) Products. The ODY MARS GAMMA RAY SPECTROMETER 5 SGS (SGS) data set is a collection of data tables that contain a gamma spectrum and the associated engineering data that has been summed over 5-degree by 5-degree latitude longitude cells on the surface of Mars and over a time period of 15 degrees of solar longitude (Ls). The SGS are produced because the individual gamma spectra collected during an approximately 19.7 second collection interval do not contain enough counts to be statistically significant. The SGS are summed over large enough and long enough spatial and temporal intervals to provide a statistically meaningful spectrum that can be used for scientific data analysis.
