Panel a: phase dependence of the PA GR corrections for different NS spin rates. Black, red, blue, and green lines show the results for ν= 1, 200, 400 and 600 Hz. The solid and dotted lines correspond to magnetic obliquity θ = 45° and 75°, respectively. Other parameters are M = 1.5 M_⊙, R = 12 km, and inclination i = 60°. Solid and dotted lines correspond to θ = 45° and 75°, respectively. Panel b: same as panel a, but for different NS radii. Black, red, and blue lines show the results for R = 10, 12, and 14 km for spin ν= 600 Hz.
