Pulse phase-resolved, energy-dependent polarimetric results. Top panels: Normalized pulse profiles in three energy bands. Middle panels: Variations of PD with pulse phase. Bottom panels: Variations of PA with pulse phase. The 2–4, 4–6, and 6–8 keV bands are shown in the left, middle, and right columns and are color-coded in green, orange, and red, respectively. The solid curves in the bottom panels represent the best-fitting single-component RVM models applied to the PA data.
