Fig. 4.
Parameters extracted from Lorentzian fits of divergence power spectra and the average convection cell evolution (see Sect. 4.2) for fast tracking rate at the solar equator, as a function of spatial scale. Values for kR⊙ > 271 are omitted as the fits are not stable in that regime. For f0 the dispersion relations from Gizon et al. (2003) and Schou (2003) are overplotted for comparison.
