Top: change of the Fe II line from emission to absorption (and vice versa) in an interval of ±80 s before and after a 3% emission event of the Fe II line at time step j. The intensity thresholds for emission and absorption are 1.5% above or below the local continuum. The vertical axis denotes the number of emission or absorption features found at each time step. Bottom: the same relation, but for a set of arbitrarily chosen control locations.
