VizieR Online Data Catalog: Origin of Metals around Galaxies. I. (Mas-Ribas+, 2018)
Abstract
Our data are composed of four high-resolution quasar spectra data sets: we use the continuum-normalized spectra of the 170 quasars in the first public data release of the Keck Observatory Database of Ionized Absorption toward Quasars (KODIAQ DR1; O'Meara+ 2015, J/AJ/150/111), and those of the 130 additional quasars incorporated in the second public data release (KODIAQ DR2; O'Meara+ 2017, J/AJ/154/114). We also consider 414 and 71 quasars with continuum-normalized spectra from observations with the Ultraviolet and Visual Echelle Spectrograph (UVES) at the Very Large Telescope (VLT), and the High Resolution Echelle Spectrometer (HIRES) at Keck, respectively (Murphy+ 2003, J/MNRAS/345/609; Murphy+ 2018, in preparation; King+ 2012, J/MNRAS/422/3370).
