Notes. Each row refers to a set of modes with different m values. Shown in Col. 2 are the volume-integrated kinetic energies of each mode integrated over m (Emode) normalized by the total fluctuating kinetic energy Eall. Shown in Cols. 3 and 4 are the maximum flow amplitudes vmax of the extracted modes at m = 2 and m = 16, respectively. Shown in Cols. 5 and 6 are the e-folding lifetimes τmode = 2/Γmode of the m = 2 and m = 16 modes, where Γmode/2π is the mode linewidth (full width at half maximum).
