The secular time variations of Ip (upper panel) and FWHM (bottom panel) of the Hα line. The time on abscissa is in RJD = HJD-2 400 000. The open symbols denote measurements from the Ondřejov Reticon detector, capable of distinguishing only 4000 intensity steps, which is why these measurements deviate systematically from the rest. See the text for details.
