Full V-band light curves (top panels) and amplitude and period data (bottom panels) of largest spots for V889 Her (left panels) and LQ Hya (right panels). The reference times t₀ in the light curves are 2 449 481 and 2 447 141 JD for V889 Her and LQ Hya, respectively. Mean magnitudes M₀ have been subtracted from both data sets. The periods and amplitudes are shown for T_s = 15 days.
