Notes. We indicate the growth rates for: Emag (r), ωrms (rω) and ωrms during the winding phase (rω,sat); see Fig. 7 for the time evolution. The other columns are similar to the ones found in Table 2 taken as an average before the dynamo instability, with the exception of the last two, which includes the Helmholtz decomposition averages before and after the instability. These are all the dynamo runs in Table 6, except M_0A010_128, M_0A015_128, and M_0A050_128, because of similar parameters with lower resolution, and except M_0A100_128, because the system crashed after the flow became supersonic.
