Folded γ-ray light curves with orbital phase zero at the maximum of the HE γ-ray emission (MJD 57 410.25). For better readability two orbits are shown. The black points (left y-axis) represent the VHE light curve (this work), the grey points (right y-axis) representthe HE light curve (from Corbet et al. 2016, Fig. 3). Error bars represent 1 σ statistical uncertainty. For the phase bins without significant detection, upper limits (at 95% confidence level) are given. The labels at the data points indicate the statistical significance of the excess in each phase bin. The blue horizontal lines denote the upper limit (at 95% confidence level) on the flux in the off-peak region (orbital phase 0.4 to 1.2).
