Most stars in this sample were observed with the Space Telescope Imaging Spectrograph (STIS) and Advanced Camera for Surveys (ACS) on the \\emph{Hubble Space Telescope} (\\emph{HST}). We find strong correlations among the \\ion{O}{1} $\\lambda$1304 triplet, %\\ion{C}{2} $\\lambda$1335, the \\ion{Si}{4} $\\lambda\\lambda$1394/1403 doublet, the \\ion{C}{4} $\\lambda$1549 doublet, and the \\ion{He}{2} $\\lambda$1640 line luminosities.
