CARMENES VIS measurements of EV Lac. RV–CRX (left), RV–dLW (middle), and RV– log L_Hα∕L_bol (right) scatter plots. Points are color-coded according to their log L_Hα∕L_bol value, with Hα enhancement of > 0.25 dex colored red. The CARMENES star id (Karmn) and the log(p-value) of the linear RV–CRX correlation are shown in the left panel. At least eight epochs of enhanced chromospheric activity can be seen via their higher Hα emission, with the highest one belonging to a strong flare event. The outliers at the bottom of the left and middle panels belong to this event (see Fig. 4 for its Hα profile).
