Fig. 4


Light curve with a binning of three months of the Fermi-LAT data between 1 GeV and 300 GeV. The downward pointing arrows correspond to a 95% upper limit. The vertical lines indicate beginning and end of the MAGIC observing window in 2011. The emission is consistent with a constant flux, although a trend towards a higher flux in the last bin, partially coincident with the MAGIC observations, is evident.
