We present a high-energy study of the intriguing COS–B \gamma -ray field , 2CG 075+00 , in order to search for possible counterparts .
New EGRET data show that the COS–B emission probably corresponds to two localized \gamma -ray sources , 3EG J2016+3657 and 3EG J2021+3716 .
Spectral fits to these EGRET sources , assuming a power-law model , yield photon indices of \sim 2 for each object .
We examine archival ROSAT and ASCA X-ray data which overlap both EGRET error boxes , and find several point sources in the region to a flux limit of approximately 6.5 \times 10 ^ { -13 } erg cm ^ { -2 } s ^ { -1 } .
We conclude that the most probable candidate for 3EG J2016+3657 is the compact , variable , flat-spectrum radio and millimeter source B2013+370 ( G74.87+1.22 ) which has blazar-like properties .
The other source , 3EG J2021+3716 , remains unidentified .
