Fig. 2


Observed (red filled triangles) VHE γ-ray differential spectrum of 1ES 1011+496 from 2011 and 2012 MAGIC stereo data. The spectrum is fitted by a simple power law (red solid line) whose parameters are indicated in the inlet. For comparison, the differential spectra (gray and black circles) from mono observations in 2007 (Albert et al. 2007a) and 2008 (Ahnen et al. 2015) and the Crab Nebula spectrum (pink dashed line) are also plotted (Aleksić et al. 2015a).
