Fig. 1
Light curve computed with the Fermi-LAT data above 100 MeV (top). A close-up is made on both P1 above 5 GeV and P2 above 10 GeV and their corresponding Gaussian fits (bottom), with resulting χ2/d.o.f values of 61/26 and 32/29 for P1 and P2, respectively. The vertical black lines define the signal regions, while the vertical red lines define the off-pulse region used to determine the background.
