Planetary Plasma Interactions (PPI) node.

These data were originally archived under PDS3 in the following volume:

General Comments                                                               
                                                                               
NOTE 2015-05-27: It was discovered that there was an error in the              
DATA/*/*.LBL files.  The keyword FIELDS had a value of 87. The actual data     
has 25 fields and the labels describe 25 fields.  This was corrected by        
changing the value of the keyword FIELDS to 25.                                
                                                                               
NOTE: On May 28, 2015 it was discovered that the pointer to the data files     
used incorrect units for the offsets for the start of objects.  Prior to       
that date pointers used offsets in rows, which is not allowed for              
spreadsheet objects.  Spreadsheet objects require pointer offsets to be        
given in bytes since the record length is variable.                            
                                                                               
NOTE:                                                                          
During the migration from PDS3 to PDS4 the above mentioned issues have been    
resolved in the migrated labels. Also discovered was a discrepancy between     
the PDS3 label data headings and CSV data headings. Please refer to the        
migrated PDS4 xml label files for the appropriately matching headings to       
data.                                                                          
                                                                               
During the migration, some data products found in the Angle Image Average      
(data-iangave_*) collections had data that occured during the INCA out of      
calibration periods. These products have been removed.                         
                                                                               
The formatting was modified in the following data products:                    
IANGAVE0_M_2015002_02.CSV                                                      
IANGAVE0_S_2015002_02.CSV                                                      
IANGAVE0_S_2015003_02.CSV                                                      
IANGAVE0_T_2015002_02.CSV                                                      
IANGAVE0_T_2015002_02.CSV                                                      
The files were modified to correctly fit the headings in the CSV files.        
The data values themselves remain unchanged.                                   
                                                                               
For documentation purposes, the browse collection: Cassini MIMI INCA ENA Sky   
Map Movies at Saturn (urn:nasa:pds:cassini-mimi-inca-cal:browse-ienamv-movies) 
are browse products but labeled as document products because MPEG-4 files are  
not supported under Product_Browse.                                            
                                                                               
The valid maximum 65535 is the largest value available for a 16-bit number.    
                                                                               
There were instances during the mission when INCA data was corrupted by bad    
memory locations in the Cassini SSR. The valid maximum '1000000.0' is a flagged
value by the instrument team where excceding this maximum would result in      
unphysically high values for the derived intensities which indicate corrupted  
data.
