Erratum: Multiyear search for a diffuse flux of muon neutrinos with AMANDA-II [Phys. Rev. D 76, 042008 (2007)]

Abstract:

A search for TeV-PeV muon neutrinos with AMANDA-II data collected between 2000 and 2003 established an upper limit of E2 90% C: L:< 7: 4 10 8 GeV cm 2 s 1 sr 1 on the diffuse flux of extraterrestrial muon neutrinos with a/E 2 spectrum between 16 TeV and 2.5 PeV. The upper limit calculation correctly included event simulations and remains as stated. However, the calculation of the detector’s efficiency, which is based only on simulations, was incorrectly tabulated in an appendix and shown in a figure. The values were approximately a factor of 10 too high, although the exact error varies in each bin. The correction has been applied in Tables I and II and Fig. 1. The effective area is the equivalent area over which the detector would be 100% efficient for detecting neutrinos. The typical uncertainty on the effective area from simulation statistics is lowest between 105 GeV and 106 GeV (2%). The uncertainty increases …
