COMMENT COMMENT This file makes use of the proposed FITS hierarchical grouping COMMENT convention (Jenings, Pence, Folk and Schlesinger, 1995). COMMENT The first 6 FITS extensions contain group tables (grouping COMMENT structures). Group table 1 is the master group table that COMMENT lists all of the other groups in the file. Group tables 2-5 COMMENT define the HDUs that comprise the four EGRET energy map sets. COMMENT Group table 6 points the the HDUs that belong to the EGRET COMMENT rationalized data format (RDF) set. Allgroup members reside COMMENT in this file; therefore, this file has only self-contained groups.
