| Description: ! These data are from the Compton GRO EGRET team. Data are from all pointings of the EGRET instrument in the verification phase and phase 1-4 of the Compton mission. The maps exist in energies 30-100 MeV, 100-100000 MeV, and as a multi-dimensional, 10 channel survey. For the multi-dimensional survey, channels 1-3 comprise energies less than 100 MeV, and channels 4-10 comprise energies greater than 100 MeV. Note that the energies are not uniformly split among the channels. P The EGRET 3D map is comprised of ten channels with the following energy ranges: UL LIChannel 1 30-50 MeV LIChannel 2 50-70 MeV LIChannel 3 70-100 MeV LIChannel 4 100-150 MeV LIChannel 5 150-300 MeV LIChannel 6 300-500 MeV LIChannel 7 500-1000 MeV LIChannel 8 1000-2000 MeV LIChannel 9 2000-4000 MeV LIChannel 10 4000-10000 MeV /ul p The default two dimensional image for the EGRET 3D survey is an average of Channels 4 - 10 (energies greater than 100 MeV). ]] |
