Correlations between line depth, FWHM, and integrated flux and S-index for each of the four lines that we found to be strongly correlated with the S-index in all three of our measured line parameters, which do not also appear in the line list published by Wise et al. (2018). These lines are newly identified activity-sensitive lines that trace activity in several different line features.
