Meridional plot of the large scale, zonally-averaged toroidal field (panel A)) and zonally-averaged radial field (panel B)), extracted at t = 534 yr, a cycle maximum indicated by the vertical dotted black line in Fig. 1. The color scale on the right is in Tesla. The bounding boxes represent the integration regions for the proxies computation, individually for the northern and southern hemispheres. The dashed circular arc corresponds to r/R_⊙ = 0.718, the interface between the convecting layers and underlying convectively stable fluid.
