Symmetry coefficients σ_ϕ and ι_ϕ in our set of 2D simulations, averaged over representative time intervals; colors indicate the initial midplane magnetization β, blue corresponding to B_z< 0; runs in [ 1,10 ] au are plotted with circles, runs in [ 10,100 ] au are plotted with squares; different background colors correspond to different disk-corona temperature contrast k; the error bars correspond to standard deviations over time.
