From Aleksic et al. (2016):
- The mean flux above 150 GeV during 2011-2012 corresponds to (4.53
+/- 0.50)% of the Crab Nebula flux

Source Classification<:
From Ahnen et al. (2016):
- "We also performed a study on the source classification. While the
optical and X-ray data taken during our campaign show typical
characteristics of an HBL, we suggest, based on archival data, that
1ES 1011+496 is actually a borderline case between intermediate and
high synchrotron peak frequency BL Lac objects."
