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>
<LI>Channel 1 30-50 MeV
<LI>Channel 2 50-70 MeV
<LI>Channel 3 70-100 MeV
<LI>Channel 4 100-150 MeV
<LI>Channel 5 150-300 MeV
<LI>Channel 6 300-500 MeV
<LI>Channel 7 500-1000 MeV
<LI>Channel 8 1000-2000 MeV
<LI>Channel 9 2000-4000 MeV
<LI>Channel 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).
