Table 1: Summary of the measured rms velocity and normalized $\alpha$ s for kinetically and magnetically forced runs, together with the resulting Strouhal numbers and their corresponding errors obtained by taking the extrema from 5 separate averages over 1/5 of the full time series. Values in parenthesis show departures from the trend and should be regarded as uncertain. For $k_{\rm f}=1.5$ the resolution varies between 64³ and 512³meshpoints for $\eta =2\times 10^{-3}$ and $2\times 10^{-4}$ , respectively, while for $k_{\rm f}=5$ the resolution varies between 32³ and 256³meshpoints for $\eta =5\times 10^{-3}$ and $5\times 10^{-4}$ , respectively.
