Top panel: radial velocity of LQ Hya from cross correlation with a synthetic template. Because LQ Hya is a single star, its rotational modulation is a consequence of the asymmetric distribution of spots. Middle panel: effective temperature of LQ Hya calculated for each spectrum with the synthetic spectrum-fitting tool PARSES. Bottom panel: rotational modulation of the V-band photometry contemporaneous to the spectra. Average error bars are given at the left side of each panel.
