Fig. 2From: Effect of core electrical conductivity on core surface flow modelsMean toroidal and poloidal velocity with respect to the core electrical conductivity. Circles and error bars represent means and \(\pm\) standard deviations, respectively, obtained for COV-OBS. x1 ranging from 1880 to 2015, at a \(r={r}_{1}\) and b \(r={r}_{2}\)Back to article page
