Distribution at constant radius of the radial magnetic field, B_r, in the vicinity of the front of the jet torsional magnetic wave, at three different times: t = 5400 s (top left panel), t = 10 100 s (top right panel), and t = 13 900 s (bottom left panel) for the Hβ simulation. For the one-dimensional probe delineated in blue in the 2D radial magnetic field cut at t = 10 100 s, synthetic data for various quantities B, B_r, B_t, and V, V_r, V_t are presented in two separate graphs (bottom right panels).
