Measured broad Hβ line parameters during the monitoring period (from up to down): Intensity (first panel), FWHM (second panel) and FW10%M (third panel), asymmetries measured at FWHM (forth panel), and FW10%M (fifth panel). The used notation is: blue represents the maximum activity (> 0.7I_max), red the extreme minimum activity (< 0.3I_max) and black represents observation between these two activity phase (0.3I_max < I < 0.7I_max).
