     The CATALOG directory on this CD-ROM volume contains the completed       
catalog objects associated with the SL9 HST WFPC2 data set.  These objects    
contain high-level descriptions of the data set.  Each catalog object is in   
ASCII, with a maximum of 78 characters per line.  Each line is delimited with 
a carriage-return (ASCII 13) line-feed (ASCII 10) pair.
