Axisymmetric (m = 0, left) and non-axisymmetric (m ≠ 0, right) magnetic field decomposition variations with the Rossby number. No clear differences are seen between the two field components; the purple fit exponents in the low Rossby number regions being close and negative, with at best a tendency for the field to be more axisymmetric for larger Rossby number values. An inverse trend is also seen for large Rossby numbers, as was expected from the previous analysis. Symbols have the same meanings as in Fig. 8.
