The CALIB directory contains the files used to reconstruct and/or             
reprocess IRAS Additional Observations and Survey Scans that contained        
comet 9P/Tempel 1.  The directory also contains logs generated by the         
processing softwares.  These logs do not have PDS labels but are listed       
in the /CALIB/AO/MANIFEST.TAB and /CALIB/SURVEY/MANIFEST.TAB.  The logs       
have self-explanatory headings.                                               
                                                                              
Russ Walker provided all files in the CALIB directory.
