high redshift (z~6) quasars (ESI)

This data set contains 34 quasars at high redshift, i.e. 5.77<z<6.54, that were taken with the Echellette Spectrograph and Imager (ESI) at Keck II. The data was taken between the years of 2002 and 2016 and in most cases multiple exposures have been co-added to increase the S/N. The data release is described in Eilers et al. 2018. 

All spectra are reduced, flux-calibrated, co-added and continuum fitted. Each file contains four columns for wavelength, flux, noise, and the continuum estimate.
