Contribution of major Fe Kα lines to the total observed line profile is plotted by the solid black line. Lines emitted locally at 6.63 keV (cyan), 6.667 keV (green), 6.682 keV (orange), and 6.7 keV (brown) are contributions from the different ionization states of FeXXV, while the line at 6.957 keV (red) is the contribution from the FeXXVI ion. The continuum level is arbitrarily lumped together for better visualization. Different panels are for various spin values marked in the boxes, all for θ_obs = 15°. The vertical dashed line marks the position of 6.4 keV energy.
