            <description>                                             
The Galileo Venus PLS data includes full resolution electron, positive ion,                
and mass spectrometer observations obtained obtained during the               
~ 3-hour 42-minute period that the Galileo plasma analyzer was                
operated at Venus.                                                            
                                                                              
The spectrogram includes all available Low Rate Science data                  
within the interval of time covered. Data with incorrect parity              
have been excluded.                                                           
                                                                              
During the Venus flyby the PLS sunshade was in the deployed                   
position. The fields-of-view of detectors 7P, 7E, 3MI and 3MD are             
obstructed by the sunshade in this configuration. No data were                
taken using these sensors.                                                    
                                                                              
The intensities measured by the seven positive-ion sensors are                
plotted on the left side of the display and the corresponding                 
seven electron sensors are on the right. Responses are averaged              
over one spacecraft rotation, approximately 19 sec, and are color             
coded according to the color bar at the top of the display.                   
                                                                              
The abscissa is spacecraft clock (SCLK) in units of RIMs:                     
1 RIM = 1.011 minutes. The ordinate of each panel is                         
energy-per-unit-charge on a logarithmic scale, covering the                   
range 0.7 ev/q to 51 kev/q.                                                   
                                                                              
The responses of the three mass spectrometers are presented on                
the bottom of the display. The abscissa is logarithmic in                    
electromagnet current while the ordinate is                                   
energy-per-unit-charge. Responses are summed for the day and                 
color coded.                                                                  
                                                                              
During this interval the spacecraft Z-axis is pointed radially                
away from the Earth. Thus detectors 7P, 7E, and mass                         
spectrometer 3 (sensors 3MD amd 3MI) are generally pointed in                 
the solar direction.</description>
