Venn diagram of our seven line lists and the number of lines in each list. All numbers/line lists are exclusive; i.e., we found nine lines correlated with the S-index in all three parameters (depth, FWHM, and integrated flux), 55 lines correlated with the S-index in depth and FWHM only, 79 lines correlated with the S-index in depth and integrated flux only, six lines correlated with the S-index in FWHM and integrated flux only, and 167, 131, 44 lines respectively correlated with the S-index in depth, FWHM, or integrated flux only.
