Collection Overview
=================
                                   
This file is a listing of particle energy spectra from the Galileo Plasma    
Instrument (PLS).  Detector reponses from ion detetors 2P, 4P, and 6P, and   
from electron detector 4E are available through the PDS as separate files.   
The energy resolution, angular fields of view, and nominal geometric factors 
for the detectors are specified in the Instrument Description file.          
                                                                             
For each detector the responses (Counts/Sample-Period) are given             
for a series of energy-per-unit charge steps (E/Q, Volts). These            
responses are summed over spin sectors. The instrument is programmable,     
and operating modes are tailored for different mission phases to acquire
effective measurements. The E/Q steps and Sample Periods for different      
mission phases (through Ida) are tabled below.

The Venus data set has several data gaps due to missing data and data    
hits.
