   All     CATALOG/TARGET.CAT is provided as a convenience to users.  The     
  Volumes   values included do not meet any particular acceptance standard,   
            and the file is not updated on any regular schedule.  Users       
            needing values to high accuracy/reliability should confirm        
            numbers in TARGET.CAT against another source.  TARGET.CAT was     
            not used during the archiving process.                            
                                                                              
           CALIB/PCK7323A.TPC is also somewhat out of date.  New constants    
            were adopted by the IAU in 2000, but a new PCK file has not been  
            created by NAIF.                                                  
                                                                              
ODRS_0001  This volume was incorrectly labeled ODY_0001 when mastered.  A new 
            version (ODRS_0001;2) was created on which this error and several 
            of the others noted here were corrected.  Note that ODRS_0001;2   
            will have INDEX, AAREADME.TXT, and ERRATA.TXT files which cover   
            more than the first volume.                                       
                                                                              
ODRS_0001  AAREADME.TXT is not clear regarding the coverage of this data set. 
   thru     Data were collected starting about 2002-01-01, during the final   
ODRS_0004   stages of ODY aerobraking.  The Mapping Phase of the mission began
            in mid February 2002.  So the majority of data are from Mapping,  
            but a few of the early files cover Aerobraking.  Corrected on     
            ODRS_0001;2.                                                      
                                                                              
           Lines in CALIB/PCK7323A.TPC are delimited by two ASCII carriage    
            returns and an ASCII line feed.  The extra carriage return was    
            removed starting with volume ODRS_0005.  Corrected on ODRS_0001;2.
                                                                              
ODRS_0003  This is the first volume containing TDF files.  The first file in  
            this set was mistakenly named 2037039B.TDF because a test entry   
            had not been removed from the data base.  There is no 2037039A.TDF
                                                                              
           The two RSR files on this volume cover deployment of the high-gain 
            antenna.  2037030A.RSR data were collected at DSS 14 using a      
            2 ksps sampling rate with 16-bit I and 16-bit Q samples.  The     
            same parameters were used at DSS 43 for 2037030B.RSR.  For unknown
            reasons, the DSS 43 data have significantly higher signal-to-noise
            ratio.  Data were also collected at 16 ksps; see ODRS_0005 and    
            later volumes for those files.                                    
                                                                              
ODRS_0005  These RSR files were collected at DSS 14 using 16 ksps 16-bit I/Q  
            samples and cover deployment of the high-gain antenna.  There is  
            a gap of 27 minutes 31 seconds between 2037030C.RSR and           
            20370413.RSR.  Reason for the gap is unknown, but it was repeated 
            on several queries spaced over several days.  Before the data     
            could be returned from the station via ftp, RSR engineers erased  
            it.  16 ksps data were collected at DSS 43 (see 2037030D.RSR and  
            20370430.RSR on later volumes) with no gap; 2 ksps data were      
            collected at both stations (see 2037030A.RSR and 2037030B.RSR on  
            ODRS_0003).                                                       
                                                                              
           The lower right panel in BRO/2037030C.PS1 shows 20370305.RSR as    
            the source file for these plots.  The correct source file is      
            2037030C.RSR.
