Abstract
We have analyzed 369 high-resolution, high signal-to-noise ratio (S/N) quasar spectra obtained with the High Resolution Echelle Spectrometer (HIRES) spectrograph and the Ultraviolet and Visual Echelle Spectrograph (UVES) spectrograph from the Keck and Very Large Telescope (VLT) observatories, respectively. The wavelength coverage of the spectra spans approximately 3000-10000Å, though there is variable coverage in this range from spectrum to spectrum. (R=36000).
