Pulse profiles of the observed flux, PD, and PA for two antipodal spots shown for three different energies (2, 5, 8 keV). The solid black curves correspond to the total flux (PD, PA), the dashed blue lines correspond to the contribution from the primary spot, and the dotted red lines are for the secondary spot. The dash-dotted gray lines correspond to the Thomson model from Salmi et al. (2021; combined from two spots). The NS parameters in both models are those shown in Table 1 of Salmi et al. (2021).
