This file reflects the minor changes made to the dataset, provided by ESA, prior to archiving at SBN.

File: CATALOG/DATASET.CAT
Changed: Updated CITATION_DESC to show the year "2013" instead of "2009" and reflect AST2 data set instead of AST1.  Removed the ARCHIVE_STATUS field.  

File: .PDSVOLUME.XML
Change: Removed the file since it is a non-standard PDS file.  It is used for ESA internal processes.
