γ-ray spectrum of PG 1553+113 recorded by Fermi (blue data points) during the IC-40 observations, compared with the IC-40 sensitivity. Cyan points are MAGIC data from Albert et al. (2009). The red thick curve is the IC-40 sensitivity envelope. The vertical line shows the maximal energy to which the powerlaw type neutrino spectrum could extend.
