Light curves derived from the observations described in Sect. 2 from MJD 55 250 to MJD 55 700 (corresponding to the H.E.S.S. measurements). The top panel presents the H.E.S.S. integral flux for E> 130 GeV where the horizontal bars represent the observing duration elapsed between the two successive full moon periods when H.E.S.S. observed the target. The bottom panel gives the Fermi-LAT  300 MeV–300 GeV flux, with 95% confidence level upper limits for segments where TS < 10 and the horizontal bars show the 14 day Fermi-LAT  integration times. This sample is typical from what was seen throughout the quiescent state.
