The CATALOG directory contains high-level catalog objects for the             
archive of the ground calibration data acquired during the second             
thermal-vacuum test (TV2) of Deep Impact instruments (HRII and HRIV).         
These catalog objects are often updated as more precise information           
becomes available.  For the latest versions of these files, please
