Comparison between Keplerian velocity v_K and average azimuthal velocity ⟨v_φ⟩ as 1D masks.(a) Pressure profile in arbitrary units. (b and c) Azimuthal velocity cross-sections, with offsets (masks) v_K and ⟨v_φ ⟩, respectively. The average ⟨V −mask⟩ is indicated by a thick black line, while shadows show the amplitude and standard deviations in blue (V = v_φ), and orange (). Data are taken at t = 200 orbital periods (inspiration for this figure was drawn from Teague et al. 2018a).
