Equivalent width (EW) ratios between epochs of the Li I 670.78 nm line (top panel) and Ca I 422.67 nm (bottom panel) photospheric absorption lines. Ratios are calculated with respect to the brightest epoch. Results show that in all cases EW changes are within 10%. Dotted black lines are at ratios equal to 1, signifying no change in the EW.
