This directory contains a PDF presentation and an archive ZIP file.  The PDF
file outlines the results of a synoptic study of Dynamics Explorer (DE 1) Retarding Ion Mass
Spectrometer (RIMS) moments calculations for 5 ion densities and temperatures.  The ions 
included are H+, He+, He++, O+, and O++. 

The the archive file named synoptic_study.zip contains *.txt files that contain means and 
standard deviations of ion densities and temperatures as functions of L-shell, f10.7, and time.  

The file names indicate the nature of the fits that are provided. 
	HpN = H+ density
	HepN=He+ density
	HeppN=He++ density
	OpN=O+ density
	OppN=O++ density
	T is used instead of N to indicate temperature.

Refer to the PDF for a synoptic review of this dataset and for the associated plots.  

Where linear fits have been performed, they are provided in the PDF on the included plots.
