Data points: Fermi/LAT spectra of the 1, 2 and 4 degree regions in the Cygnus region (from bottom to top). Straight lines show fits to the spectra with extrapolations to higher energies. Curves represent the 90% confidence level. sensitivities of IceCube (2 yr exposure) for the extended sources of the size 1, 2 and 4 degree (from bottom to top) for all neutrino flavors, assuming that at Earth, after oscillations, the muonic neutrino flux is one third of the total neutrino flux (Learned & Pakvasa 1995). The horizontal hatched region shows the spectrum of the VHE γ-ray source MGRO J2019+37. The vertical hatched region shows the spectrum of MGRO J2031+41. The gray shading shows the sum of the fluxes of MGRO J2019+37 and MGRO J2031+41 (Abdo et al. 2012); both sources are within the 4 degree source region considered for spectral extraction in Fermi/LAT.
