Boundaries for the integration of the power spectral density.

νinf(n, ) νsup(n, )
 = 0 (νn, 0 + νn − 1, 2)/2 (3 νn − 1, 3 + νn, 0)/4
 = 3 (3 νn − 1, 3 + νn, 0)/4 (7 νn − 1, 3 − νn, 0)/6
 = 1 (7 νn − 1, 3 − νn, 0)/6 (4 νn − 1, 2 − νn, 0)/3
 = 2 (4 νn − 1, 2 − νn, 0)/3 (νn, 0 + νn − 1, 2)/2

Notes. The boundaries are equivalent to the mid-point between consecutive modes, except when  = 1 and  = 3 modes are involved. This is illustrated in Fig. 2. The boundary between the  = 1 and the  = 3 modes is chosen close to the  = 3 mode frequency. We made this choice to avoid any confusion between a  = 3 mode and the neighbouring dipole mixed-modes because the dipole mixed-modes extend up to the  = 3 modes.
