Top panel: Fermi LAT γ-ray phasogram from Abdo et al. (2009b), 20 bins per period. Middle: pn X-ray lightcurve of J1614−2230 (0.4−3.0 keV) overplotted with the model and parameters described in Sect. 4 (black solid line). The phasogram is shown with 16 bins per period and the dotted line corresponds to the background level. The error bars indicate the statistical 1σ error. Bottom: the Nançay 1400 MHz radio lightcurve. All plots show absolute phase.
