Fig. A.1
Top: eigenvalues (
) of the gravity and Rossby modes of lowest degrees (− 6 ≤ n ≤ 5) as functions of the spin parameter (ν). The horizontal axis represents the function of ν given by 
, and the vertical axis the function of given by 
. Bottom: projection coefficients 
of the normalized Legendre polynomial 
on normalized Hough functions associated with these modes as functions of the spin parameter (see Eq. (70)).
