Results of the phase-resolved spectral fits using 100 phase-bins with NuSTARdata only. Panel a: Flux between 3–20 keV in keV cm^-2 s^-1. Panel b: Photon index. All other continuum parameters were frozen to the phase-averaged value. The orange dashed line indicates the dip to guide the eye. Panel c: value for each phase-bin. The blue dotted line indicates the average overall bins.
