2001 Mars Odyssey: GRS
Special Products
|
Jan. 20, 2026. GRS Special
Products have been migrated to PDS4. |
The Odyssey GRS Science Team 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 Science articles published in 2002 by the
GRS Team were based on these data.
Data files (*.tab) are tables with fixed-length fields separated by commas.
Each data file is accompanied by a PDS4 label (*.xml) that describes the format
of the data file. (Legacy PDS3 labels (*.lbl) from the original version of this
dataset are also present.) Both the data and the labels are ASCII text files.
