Table 1.
Mean-field pattern periods for Pm = 4 and Pm = 90.
| Pm | Pabove | Pbelow | PαΩ, N | PαΩ, S |
|---|---|---|---|---|
| – | [orbits] | [orbits] | [orbits] | [orbits] |
| 4 | 8.33 | 5.47 | 6.2 | 6.23 |
| 90 | 5.55 | 3.73 | 4.9 | 4.03 |
Notes. Periods are measured above (i.e., N for north) or below (i.e., S for south) the midplane (z = 0). The period is estimated by taking the FFT of 
at |z|=2H. In particular, PαΩ is the theoretical period taken with the maximum value of αyy above or below the midplane.
