Subtraction of the non-active, lithium-poor template (red line) from the spectrum of S 435 (black dots), which reveals the chromospheric emission in the Hα core (blue line in the bottom panel) and emphasizes the Li Iλ6708 Å absorption line, removing the nearby blended lines (top panel). The green hatched areas represent the excess Hα emission (bottom panel) and Li I absorption (top panel) that were integrated to obtain and WLi, respectively.
