Notes. Parameters ω_m (mode frequency), Γ_m (full width at half maximum), A (maximum height of the Lorentzian function), and B (background power) that give the best fit to the power spectrum for each m in the range 3 ≤ m ≤ 15. The frequency ν_start defines the frequency range [ν_start, ν_start + 300 nHz] for the Lorentzian fit. The 68% confidence interval on each parameter is indicated by the upper and lower bounds estimated from Monte Carlo simulations. The modes with m <  10 have a quality factor ω_m/Γ_m >  1 in the corotating frame (the frame for Rossby waves). However, the modes with m ≥ 10 have a quality factor less than or comparable to one. The e-folding lifetime, 2/Γ_m, is given for each mode, as well as the oscillation period measured in the Sun’s corotating frame (rotating at Ω_eq/2π = 453.1 nHz). Negative oscillation periods indicates retrograde propagation. The rms south-north travel-time shift δτ_rms for each m is obtained from the fitted Lorentzian F_m(ω)−B using Parseval’s theorem with the window function taken into account. The rms horizontal flow speed of the r modes along the equator in the near-surface layers, v_rms, is converted from the δτ_rms using conversion constants estimated from forward modeling (see text). A typical error in the v_rms is about 0.5 m s⁻¹ based on the error propagation. The maximum flow speed along the equator for each mode is related to the rms flow speed by . Also listed are the mode frequencies from Löptien et al. (2018) for comparison.
