High Redshift ESI QSO Spectra Data Release

This is the public data release (April 2015) for ESI spectra of high redshift quasars obtained by Marc Rafelski, Arthur M. Wolfe, Xavier Prochaska, and Marcel Neeleman on the Keck Telescopes. Most of these QSOs contain high redshift DLAs, which you can find in Rafelski et al. 2012 and Rafelski et al. 2014.

The table below lists the ESI spectra along with their basic properties. Please refer to Rafelski et al. 2012 and Rafelski et al. 2014 for technical details on the observations. Please cite these papers when using the data and reference this website. The spectra are fully calibrated and fluxed, but are not continuum fit. Note that QSOs without DLAs in their spectra typically have lower signal-to-noise, see above references for more information.

Individual spectra can be downloaded from the table, or the entire dataset can be downloaded here. The Plate, MJD, FiberID, z_em, r_mag, i_mag, and z_mag are from SDSS/BOSS DR12. The quasar redshift is z_em.
