| Abstract: | From the results given in a recent paper by Zaatri et al. (2006, Solar Phys.
236, 227) it is clear that foreshortening effects play a major role in estimating the magnitude and direction of meridional and
other flows in the shallow solar sub-surface layers using local helioseismology. Using a different algorithm to account for
these effects I arrive at a significantly different estimate for the meridional flows. |
