The waves are categorized into one of 4 modes (block wave_mode_clustering), shown in columns.

(A) The average wave pattern of each mode is illustrated as a time-delay heatmap with iso-delay contours. Top: number of waves contributing to the mode.

(B) The aggregated histograms of channel-wise directions during waves of each mode. The black lines indicate the average wave-wise direction measures.

(C) Map of the average channel-wise velocities $v_{\mathrm{x},\mathrm{y}}$ in waves of each mode (color code), overlayed (arrows) with the average channel-wise direction determined via the optical flow.

(D) The distributions of channel-wise velocities corresponding to (C). Black ticks and error bars: the average and $95\%$ confidence interval (CI) of the corresponding wave-wise velocities.

(E) The average and $95\%$ CI of the planarity, P, for waves of each mode.
