This is a PDS4 archive of the following PDS3 data set:                                
CO-S-MIMI-4-CHEMS-CALIB-V1.0 (https://doi.org/10.17189/1519606).                      
                                                                                      
These collections were originally archived under PDS3 in the following volumes:       
COMIMI_C001.                                                                          
                                                                                      
Under the PDS3 standard all archives were self contained and could in principle be    
stored in a single file system (disk, CD-ROM, etc.).  PDS4 takes advantage of the     
network capabilities that allow archives to be distributed.  As a result, some of     
the documents and metadata previously stored in the PDS3 catalog files are no longer  
maintained locally, but are  maintained in a central repository.  Those files are     
referenced by unique PDS logical identifiers that are included in the document        
collection inventory.                                                                 
                                                                                      
Errata
