Phase-binned H.E.S.S. flux above 190 GeV as red points. The phase errors in the H.E.S.S. light-curve points refer to the re-grouped data given in Table 1. Fermi-LAT γ-ray flux points from Balbo & Walter (2017) and Swift X-ray data from Corcoran et al. (2017) are shown as green triangles and as black line, respectively. Flux errors are all 1σ while upper limits are 95% confidence level. The X-ray data has been scaled to arbitrary units for better comparison to the γ-ray data.
