Simulated PD and normalized Stokes q and u profiles for the NS parameter set 1 (panels a and b are for the 2–8 keV and 2–5 keV energy range, respectively) and set 4 (panel c) from Table 1. The exposure time is 600 ks in all three cases. The blue lines show the theoretical model, the purple dots are the synthesized observed data, and the red dots are the MDP values for the corresponding phase bins.
