the strong clockwise rotation associated with the untwisting of the reconnected field lines.

The free magnetic and kinetic energy curves shown in Fig. \[Fig:BetaE\] all follow the typical evolution observed previously (PDD15) during the generation of the [[helical jet]{}]{}. There is a peak of the free magnetic energy, followed by a sudden drop, corresponding to the release of magnetic energy by intense magnetic reconnection (top panel). The partial transformation of magnetic to kinetic energy results in a sharp peak in the latter (bottom panel). The changes in the free energy are proportional to the intensities of the kinetic energy, as shown in PAD10. Quantitative differences are observed among the different runs regarding the [[helical jet]{}]{} trigger, however: the trigger time and the free energy levels differ from one simulation to another. Using Equation 5 of PDD15, we derive the trigger time, $T_{trig}$, and the trigger energy, $E_{trig}$, from the peak of the free magnetic energy curves (Fig. \[Fig:BetaE\], top panel). The resulting values are given in Table \[Tab:BetaParam\]. We find consistently that for increasing values of $\beta$, the [[helical jet]{}]{}tends to occur later, after a larger amount of energy has been stored.

In PDD15, we observed that the [[straight jet]{}]{}developed
