Azimuthally averaged radial profiles of residual velocity δv_ϕ and ratio δv_r in the inner 300 au for the clump-infall models. Top and bottom panels: right and left columns in Fig. 8 (or Clump2 and Clump3 bursts, respectively). The vertical dashed lines show the radial distance of the infalling clumps that cause the burst. The dash-dotted line in the bottom panel shows the radial distance of the clump (shown with the red arrow inFig. 8) participating in the close encounter that triggered the burst.
