Figure 4

Quantitative evaluation of the imaged toroidal field B T ϕ . Correspondence of the imaged toroidal field to the dynamo model toroidal field using u H at r=0.984r o in the case of (a) FR and (b) TR. The radial profiles of (c) amplitude ratio and (d) correlation coefficient. In (a) and (b), solid lines represent the amplitude ratio determined by the principal component analysis, and dashed lines represent the lines of slope one. In (c) and (d), black (gray) lines represent the case in FR (TR). Solid lines denote the mean values and dashed lines denote the mean ± 1 σ.
