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.
