The x- and y-axes indicate the indices l and m, respectively, while the colors represent the absolute magnitude of the multipolar coefficients, ﹩| {a}_{lm}^{B,{\rm{in}}}| ﹩, on the stellar surface. The log-linear color bar shows the true values. Each panel corresponds to one of the vacuum solutions of CK21. All m = {0, …, l} cases are shown up to l = 20.
