The BROWSE directory contains Quick Look Browse Plots of the data. The plots  
are available as jpeg (*.JPG) files. There may also be postscript versions of 
the plots (*.AUX). The plots are accompanied by a single label file of the    
same file name but with extension *.LBL.                                      
                                                                              
The files contain either quick look views after early processing of raw data  
(RSR i.e. Radio Science Receiver data) or quick look plots of calibrated level
 2 data (IFMS). These may be useful in identifying data which deserve more    
detailed inspection. Certain data anomalies can be readily seen in the plots. 
More details are given in the label file (*.LBL) of each plot.                
                                                                              
JPEG files contain several figures generated from level 2 Doppler data after  
processing and calibration. These may be useful in identifying data which     
deserve more detailed inspection. For example, by looking at the JPEG file,   
the user can determine whether a signal was easily detectable or whether the  
data were corrupted. Certain data anomalies can be readily seen in the plots. 
                                                                              
AGC that is the Auto Gain Control [dBm] corresponds to 'SIGNAL LEVEL' in the  
LBL file accompanying the level 2 data. Also calibration [Hz] corresponds to  
'CORRECTION OF EARTH ATMOSPHERE PROPAGATION'. Residuals [Hz] correspond to    
'RESIDUAL CALIBRATED S or X-BAND FREQUENCY SHIFT'.                            
                                                                              
The panels are arranged in the following way and can be easily identified     
by the title on top of it. The plots were generated using gnuplot. Thus       
the numbers in the upper right corner in each plot thus not give a ratio      
but the number of columns plotted against each other. I.e. using 1:2 means    
that the first column of the plotting data set was plotted against the        
second column.                                                                
                                                                              
However this plotting data set is a subset of the complete data set given     
in the corresponding level 2 data file. The raw data set contains not all     
columns of the level 2 data. For example not all time columns were used       
since only time in UTC was needed. In the filtered                            
plotting data set in addition data points  some data points that were         
identified as cycle slips were removed. To see which columns of the           
level 2 data was used for plotting compare the description given below        
with the corresponding lebel 2 data label file.                               
                                                                              
Plot 1:     Auto Gain Control in dBm vs UTC time (hours of the DOY of         
            measurement)                                                      
            Sometimes no Auto Gain Control (AGC)-files are available.         
            In that case no AGC is plotted.                                   
Plot 2:     Calibration in Hz vs UTC time (hours of the DOY of                
            measurement)                                                      
Plot 3:     Complete Residual of observed and predicted Doppler shift [Hz]    
            vs UTC time (hours of the DOY of measurement)                     
Plot 4:     Complete Differential Doppler [Hz] vs UTC time                    
            (only available if both X- and S-Band was recorded) (hours of     
            the DOY of measurement)                                           
Plots 5-7:  The complete residual (above) was subdivided into three plots     
            in order to better identify smaller fluctuations which would      
            otherwise not be seen in the complete plot. Plots wich contain    
            'filtered' data are cleared from cycle-slips.                     
Plots 8-10: The complete differential Doppler (above) was subdivided into     
            three plots in order to better identify smaller fluctuations      
            which would otherwise not be seen in the complete plot.           
            Plots with extension 'filtered' are cleared from cycle-slips      
            using scripts.                                                    
            (only available if both X- and S-Band was recorded).
