COMMENT COMMENT This file makes use of the proposed FITS hierarchical grouping COMMENT convention (Jennings, Pence, Folk and Schlesinger, 1995). COMMENT The first, second and fifth through eighth extensions are COMMENT group tables. Group table 1 is the master group table that lists COMMENT all the other groups in the file. Group table 2 defines the RDF COMMENT group members. Group tables 3-6 define the HDUs that comprise the COMMENT four EGRET energy map sets. Many of the group members referenced COMMENT in this file reside in different FITS files on other computer COMMENT systems; therefore, this file is not self-contained.
