Variations in the integrated flux a) and velocity
centroid b). Dashed lines: smooth curves showing the
long-term variability (see text). Vertical bars in the top panel
show the emission minima of individual groups of features F5-F8
according of Figs. 5-8, respectively, and in the
bottom panel they denote activity cycles in which
