Comparison of the torsional oscillations derived using the LCT flow maps (vφ) presented in this study and from global helioseismology with the f-mode (provided by Larson & Schou 2017). From top down: nominal LCT vφ, LCT vφ symmetrized around the equator, LCT vφ symmetrized and convolved with the latitudinal component of the averaging kernels of the f-mode study. The bottom panel shows the results from the f-mode data. We have subtracted the mean rotation rates for all data sets.
