Map of the maximum PD in the 2–8 keV band, achievable at some rotational phases, depending on the inclination angle and the co-latitude of the spot center θsp computed for the model with the hydrogen spot hatm. The robust observational limit on the pulsed fraction of 9.7% is also shown with a thick red curve (see details in Doroshenko et al. 2022). The curves of equal PD are labeled.
