Average folded light curves in two energy ranges over the orbital period (P_orb = 15.6610 ± 0.0017 days). Phase zero corresponds to the periastron passage in the SBOP orbital solution. Red dashed lines indicate the time of possible eclipse according to this solution (φϵ [0.86 − 1.06]). Top panel: weighted folded ASM light curve (from daily average datapoints). Bottom panel: weighted folded BAT light curve (from daily average datapoints).
