PVO ORPA Data Bundle - Errata                                                                  
                                                                                               
This document describes known errors or deficiencies with files contained in the PVO ORPA data 
collections                                                                                    
                                                                                               
These data were originally archived in the following PDS Data sets:                            
PVO-V-ORPA-5-ELE_ION_PHOTO_UADS-V1.0 (https://doi.org/10.17189/1519828)                        
                                                                                               
Under PDS3, the following were known deficiencies or errors reported in the ERRATA.TXT file:   
                                                                                               
2019-11-04 - The data originally released incorrectly reported the year in the DATA files. The 
month, day, hour, minute and seconds were correctly stated, but the year was almost uniformly  
set to 1978, the year PVO arrived at Venus. During the process of correcting this error data   
was outputted in ASCII to make the data easier to use.                                   
                                                                                               
2019-11-13 - The DATA/LOW_RES/ORB_4200_4299/ 4267_ORPA_LOW_RES.TAB file was found to contain   
the word FLAG instead of a flag value. This error was corrected.                               
                                                                                               
2020-05-21 - It was discovered that the "month/day" in the time tags believed to be correct    
when the year issue was fixed in Nov. 2019 are actually off by one day. This issue was         
discovered and reported to PPI by Christopher Fowler on 2020-05-19 and the confirmed on 5/21.  
This timing error has been corrected for all files in this PDS4 pvo-orpa bundle. The 
"month/day" in the time tags that were off by one day were corrected by regenerating the data 
files, in this PDS4 bundle, and applying a shift of one day.                              
                                                                                               
                                                                                               
During the migration from PDS3 to PDS4 the following files were found to contain the word FLAG 
instead of a flag value. This error was corrected.
