Notes. Identified absorption lines and rest-frame equivalent widths (EWr, in Å) measured using the IRAF package for Best Data (average of RRM3, RRM4, and RRM5 observations) and Epoch 2. The equivalent width errors were also computed in IRAF. Lines flagged with a are blends with intervening absorption lines, as specified in the main text.
