2001 Mars Odyssey: GRS Special Products

The Odyssey GRS Science Team has released a set of special derived products to accompany the October 1, 2002, release of EDRs (raw data). These products include global maps of neutron flux and portions of gamma-ray spectra showing hydrogen peaks. Figures in recent publications by the GRS Team were based on these data. Future GRS data releases will include standard derived products in addition to the raw data.

Data files (*.tab) are tables with fixed-length fields separated by commas. Each data file is accompanied by a PDS label (*.lbl) that describes the format of the data file. Both the data and the labels are ASCII text files.
