Sample spectra near the Li I and Ca I resonance lines, as observed by UVES in 2009, in V1309 Sco (Mason et al. 2010). The observing epochs are indicated as UT times for each pair. Spectra were not normalized and, for each pair, are to scale. The area highlighted in pink is where the strongest Ca I absorption is observed and where Li I may have a weaker corresponding feature. The vertical dotted line marks the central velocity of this component. The dashed line marks the peak position of the Li I and Ca I emission lines in the 2016 spectrum.
