Run H. Upper left panel: rms values of , and u (), cf. Fig. 10. Remaining panels: selected quadrupolar moments of α_ij and η_ijk determined by the test-field method and given by , see Eq. (34); likewise for η_ijk. Normalization is by the temporally averaged u_rms, as u_rms undergoes a slow, steady drift over time. Vertical lines mark the times of events visible in the first panel.
