Axisymmetric (left panel) and nonaxisymmetric (right panel) component of the PFSS OSF (l_max = 50, R_SS = 2.5 R_⊙, blue) and the vector sum (orange). The vector sum components correspond to projections of the vector sum along (Φ sin λ, axial) and perpendicular (Φ cos λ, equatorial) to solar rotation axis. The PFSS OSF components correspond to PFSS expansion using only axisymmetric (m = 0) and nonaxisymmetric components (m ≠ 0).
