This file contains a description of the index tables created for the IRAS     
archive of comet 9P/Tempel 1 images and photometry.  A separate index table   
was created for each of the 5 data sets in this archive:

  - AO photometry tables

These index tables carry information about the scientific parameters for      
each data file.
