Fig. 8

Rotational splittings and 1σ error bars (solid red lines), constraints deduced from inequalities on pairs of modes (dotted blue lines), and constraints from multiple modes using simplex method (dashed green lines). The lighter lines denote the 1σ error bars. Right panel: zoom on ℓ = 3 mode where an inequality breaks down by 4.99σ (as indicated by the arrow). (Colour online.)
