Evolution of spectral model parameters with pulse phase (black) for Obs. II. Panels and units are the same as Fig. 7, but for Obs. II. The width of the 10-keV absorption feature was fixed to the pulse-phase-averaged value of 1.8 keV. Energies of 10-keV absorption feature are not shown where the depth is consistent with zero. All panels show the 3–78 keV NuSTAR pulse profile of Obs. II in light gray. The pulse profile model was obtained from fitting the 3.5–4.5 keV NICER pulse profile of ObsID 4201960150.
