Fig. 2
Light curves of the broad Hα and Hβ emission line fluxes, together with the continuum fluxes at 5100 Å and 6200 Å in logarithmic scale for the sample of six AGNs (object name and line/continuum denoted on each plot). Data are divided on the basis of the high-flux (triangles) and low-flux (full circles) states. Error bars are also shown, unless smaller than the marker.
