    PostScript files contain one figure each showing quick look views after   
early processing of raw data.  These may be useful in identifying data which  
deserve more detailed inspection.  For example, by printing the PostScript    
file, the user can determine whether a signal was easily detectable or        
whether the data were corrupted.  Certain data anomalies (saturation          
in the analog-to-digital converters, clipping in amplifiers ahead of the      
ADCs, receiver tuning errors, poor choices of receiver gain, etc.) can be     
readily seen in the plots.                                                    
                                                                              
    Each PostScript file is sized to fit on a single 8-1/2 x 11 inch page.    
Each landscape format page includes four panels showing:                      
                                                                              
      upper left:  a histogram of raw data samples (for high sample           
                   resolutions -- e.g., 16 bits -- the histogram plot         
                   is usually compressed by aggregating adjacent bins);       
      upper right: a sequence of average power spectra derived from the       
                   raw samples (each spectrum typically represents 60 s);     
      lower left:  averaged raw sample power versus time (typically sample    
                   power is averaged over 1 s); and                           
      lower right: an extract of the first few lines of the source            
                   RSR PDS label                                              
                                                                              
    PostScript file names have the form ydddhhmm.PS1 where                    
                                                                              
              y    is the one-digit year (0-9)                                
              ddd  is the three-digit day-of-year (001-366)                   
              hh   is the two-digit hour (00-23)                              
              mm   is the two-digit minute (00-59)                            
                                                                              
The file names are chosen so that they match the RSR file names ydddhhmm.RSR. 
Note that, on the rare occasions when there were multiple recordings of the   
the same occultation, the  mm  component may be modified in one of the files  
so that file names are unique.                                                
                                                                              
     Each panel was generated by MATLAB as a Level 1 PostScript file for      
color printers.  The panels were then assembled into single                   
page PostScript files using the psmulti utility, a PERL script written        
by D. Murray Laing.  The computing platform was a Sun Ultra running           
Solaris 2.6.  MATLAB is a technical computing environment for computation
