Table 3.

Maximal perturbative frequency deviations Δω_per/2π and maximal frequency deviations Δω/2π for frequencies of dipole modes with radial orders n ∈ [ − 50, …, −10], computed with Eqs. (14a) and (14b), for parameter variations of the reference model.

Notes. All quantities, except for B₀, M_ini and D_mix, are unitless. The influence is assessed for zonal modes (m = 0), except when varying m (m ∈ [ − 1, 0, 1]) or ℛ_rot (m = 1).
