This directory contains the original CDF format SREM data files from which    
the PDS data products have been produced.  Note that the CDF processing       
level for SREM is different to that used by PDS.  The CDF Level 0 files are   
equivalent to the PDS CODMAC Level2 data, while the CDF Level 2 files are     
equivalent to the PDS CODMAC Level 5 data.                                    
                                                                              
Note the correspondence between the CDF files and their CODMAC Level 2 PDS    
data equivalents is easily tracked through the filenames:
