Notes. We fix the dynamo number D = 2.1 × 106, and magnetic cycle periods are expressed in years, considering a diffusive time, tη = 1550 years. The period presented are extracted from surface magnetic dynamics. For some cases, a second cycle is present and its period is then indicated in parentheses. Both reference αΩ dynamos described in the previous section (Sect. 3) are shown in bold type.
