The Gamma Ray Spectrometer Experiment Data Record (GRSEDR) Neutron Spectra (NEUTNS) data products are composed of 15 histograms, event data, and the associated timing and spatial information. The neutron event data are the cumulative counts of neutrons detected at 1 of four prisms over the collection interval. The collection interval is approximately 19.7 seconds, but may vary over the course of mapping. The timing and spatial data provided with the neutron spectra includes spacecraft clock values and spacecraft spatial data. The sc_ev_time, UTC time, and geometry fields are all recorded at the center of the collection interval.

GRS NEUTNS products have the following file names:

NEUTRON_SPECTRA_yyyymmdd.DAT (with detached PDS label)

where:

yyyy = year

mm = month (01-12)

dd = day (01-31)

In ODE, NEUTRON products have the following Product IDs:

NEUTRON_SPECTRA_YYYYMMDD
