Normalised flux (lower panel), PD (middle panel), and PA (upper panel) as a function of pulsar phase for the fiducial set of parameters M = 1.5 M_⊙, R = 12 km, ν = 600 Hz, the inclination i = 60 ° , and the magnetic obliquity is θ = 45°. The dotted lines show the contribution from the primary spot, the dashed lines correspond to the secondary spot, and the solid lines indicate the results for both spots. The PA χ₀ from the RVM, as given by Eq. (30) for the primary spot, is shown by the black line. The red lines indicate the GR correction to the PA χ_c, GR given by Eq. (57) for the two spots. The blue lines show the total PA χ = χ₀ + χ_c, GR for both spots separately and together.
