The Rosetta Housekeeping data files are all stored as ASCII tables (with the  
extension TAB) in the DATA directory.  In cases where the ASCII data were     
generated from binary files, the original binary data equivalent (with the    
extension DAT)  is available in the EXTRAS directory.  All files have an      
associated detached PDS label file (with the extension LBL) containing key    
metadata required to read and interpret the corresponding data.
