ERRATA.TXT - Contains text information describing errors and/or anomalies     
found in the current volume as well as errors and/or anomalies found in       
previous volumes of a volume set.

05Mar12   Two data files were discovered to be missing labels at the time     
          these data were reorganized into the one dataset/volume format.     
          (The labels were apparently lost to media failure on the DVD-RO     
          they were originally copied to.) These data files are:              
                                                                              
             data/2000/171/cifdbl/m0136820643f4_2p_cif_dbl.fit                
             data/2000/190/cifdbl/m0138438639f4_2p_cif_dbl.fit                
                                                                              
          Labels were re-created by using the parallel /cif/ directory        
          file.  The MEAN, STANDARD_DEVIATION, MINUMUM, and MAXIMUM           
          values were not calculated for this effort, though, so those        
          keywords were deleted from the IMAGE object definition in these     
          two labels.                                                         
                                                                              
01Sep01   In the data labels on this volume, some PDS keywords may contain    
          numeric values that are used to represent the figurative            
          constants "N/A" and "UNK".  The keywords affected and numeric       
          value equivalents are as follows:                                   
                                                                              
            Keyword                       Numeric values and Equivalent

          Keywords are given the value of "N/A" in situations where the       
          computation of that value does not apply.  As an example, all of    
          the keywords related to calculations of a point of intersection     
          on a solar system body surface do not apply when the line of        
          sight for a particular instrument does not intersect the surface    
          of a body.                                                          
                                                                              
          Keywords are given the value of "UNK" in situations where the       
          information needed to calculate that value are unknown.  All of     
          the keywords above require knowledge of spacecraft orientation      
          and/or position information, as well as models of various solar     
          system bodies.  There are certain instances in time during the      
          mission when this information is unknown.
