Variations of the best-fit parameters of model TBABS × (GAU+COMPTT × GABS × GABS) as a function of pulse phase obtained from the NuObs3+P0211006008. Panels a–i: observed X-ray flux in the energy band 1–79 keV in units of 10⁻⁹ erg s⁻¹ cm⁻², first absorption feature energy in keV, width in keV, and its optical depth, neutral hydrogen column density N_H in units of 10²² cm⁻², input soft photon temperate in keV, plasma temperature in keV, plasma optical depth, and the reduced χ², respectively. The values of the red points are fixed at the best-fit values and the blue dot represents the 3σ upper limit of the first absorption feature optical depth. The second absorption feature parameters are shown in Fig. 11.
