Notes. For sg-mhd-tau20, the initial phase is I1 := [160 − 260], and the saturated phase is I2 := [800 − 1300] (see also Fig. 2). For sg-mhd-tau10, the initial interval is :=[500 − 700], but evaluated for the prolonged GI-phase (see Appendix A). For the dynamo-saturated phase, the interval :=[1000 − 1500] is used.
