As modes with L≥3 cannot
fit the observed radial-velocity amplitude for realistic values of the
pulsational velocity amplitude Vmax (see Østensen et al., today),
the only modes to be considered are those with L=0, L=1, and L=2.
For stars without significant
rotational broadening it is not possible to derive the sign of |M| .
Only 6 modes remain:
| L=0 |M|=0 Vmax = 22 km/s width = 22 km/s |
L=1 |M|=0 Vmax = 29 km/s width = 22 km/s |
L=1 |M|=1 Vmax = 34 km/s width = 20 km/s |
L=2 |M|=0 Vmax = 50 km/s width = 20 km/s |
L=2 |M|=1 Vmax = 50 km/s width = 20 km/s |
L=2 |M|=2 Vmax = 60 km/s width = 10 km/s |
