Abstract:
During its 9 year lifetime, the Energetic Gamma Ray Experiment
Telescope (EGRET) on the Compton Gamma Ray Observatory (CGRO) detected
1506 cosmic photons with measured energy E>10GeV. Of this number, 187
are found within a 1° of sources that are listed in the Third
EGRET Catalog (Cat. J/ApJS/123/79) and were included in determining
the detection likelihood, flux, and spectra of those sources. In
particular, five detected EGRET pulsars are found to have events above
10GeV, and together they account for 37 events. A pulsar not included
in the Third EGRET Catalog has two events, both with the same phase
and in one peak of the lower energy gamma-ray light curve.
