Abstract (from CDS):

Using the HEGRA system of imaging atmospheric Cherenkov telescopes, a region of the Galactic plane (-10°<b< 5°, 38°<l<43°) was surveyed for TeV gamma-ray emission, both from point sources and of diffuse nature. The region covered includes 15 known pulsars, 6 known supernova remnants (SNR) and one unidentified EGRET source. No evidence for emission from point sources was detected; upper limits are typically below 0.1Crab units for the flux above 1TeV. For the diffuse gamma-ray flux from the Galactic plane, an upper limit of 6.1x10–15ph/cm2/s/sr/MeV was derived under the assumption that the spatial distribution measured by the EGRET instrument extends to the TeV regime. This upper flux limit is a factor of about 1.5 larger than the flux expected from the ensemble of gamma-ray unresolved Galactic cosmic ray sources.
