Difference between the measured magnetic field strength (B₀′) and the actual one (B₀ = 1 MG) as a function of the obliquity angle (β). Here, A₁ asymmetries were used for n_pg = 2, and $δ \tilde{A}$ $\delta \tilde{A}$ is based on a model rotating at 5 per cent of the critical rotation frequency. The critical angle where the magnetic asymmetry changes sign is indicated with a vertical red line.
