Magnetic shift computed from the difference, δK_in for the magnetic profile U (orange), B+ (red), and B– (green), as a function of the apparent radial order, n, of ℓ = 2 modes. We notice that for the profile U, the apparent radial orders are shifted compared to the real ones (see Table 1 and text for a discussion). Dashed lines are obtained when the radial order of ℓ = 1 modes is incorrectly identified compared to the radial order of ℓ = 2 modes by ±1.
