     An overview of the processing used to take the raw data to the final     
results at Stanford University.  Limited primarily to data included in        
this archive (the 16 minutes surrounding South Pole backscatter on Orbit      
234).  Included is a description of the file naming convention.

     Abstract submitted to Lunar and Planetary Science Conference XXXI        
summarizing attempts to find a scattering function showing enhanced           
backscatter from the lunar South Pole.  This label file points to an ASCII    
text version of the abstract (LPSC_ABS.TXT) and a version in Adobe Portable   
Document Format (LPSC_ABS.PDF).  Figure 1 is not included in the text         
version, but it can be constructed from RATIOFNS.TAB in the SORT directory    
of this archive.

     A brief discussion of performance of the DSS 14 antenna during the       
Clementine bistatic radar experiment during Orbit 234.  Compares actual       
performance versus what is expected under nominal conditions.

     A discussion of steps taken to obtain system temperature of the          
DSS 14 system and to correct for changes in system gain during Orbit 234.

     A description of the format of files in the FND directory.  This         
document is an adaptation of a Unix 'man' page.  It describes both the        
header record and data records.

     A summary discussion of factors responsible for changes in carrier       
level observed during data acquisition at DSS 43.  DSS 43 collected data      
from Orbits 235 and 236.  Tables and figures were not available at the        
time the archive was constructed; but the text remains useful in              
providing a sense of why various level changes occurred.                      
                                                                              
                                                                              
DSS43TSY.TXT                                                                  
                                                                              
     A brief discussion of steps taken to calibrate the system temperature    
at DSS 43 on orbits following Orbit 234.  Since DSS 43 data are not           
included in this archive and since the DSS 43 calibration was not             
confirmed by a rigorous reanalysis, these notes should be taken with some     
caution.

     A brief description of system noise changes between when the DSS 43      
antenna was pointed at the center of the Moon and when it was pointed at      
the limb (South Pole).
