KODIAQ DR3 consists of a fully reduced sample of 727 quasars at 0.1<zem<6.4 observed with the Echellette Sepctrograph and Imager at moderate resolution (4000<~R<~10000). DR3 contains 872 spectra available in flux calibrated form, representing a sum total exposure time of ~2.8 megaseconds. These coadded spectra arise from a total of 2753 individual exposures of quasars taken from the Keck Observatory Archive (KOA) in raw form and uniformly processed using a data reduction package made available through the XIDL distribution. DR3 is publicly available to the community, housed as a higher level science product at the KOA and in the igmspec database. 2021AJ....161...45O https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/161/45 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to J/ApJ/721/1 : Keck ESI observations of Lya systems (Penprase+, 2010) J/ApJ/755/89 : Metallicities of damped Ly{alpha} systems (Rafelski+, 2012) J/ApJ/788/119 : Properties of the highly ionized gas of quasars (Lehner+, 2014) J/AJ/150/111 : KODIAQ DR1 (O'Meara+, 2015) J/AJ/154/114 : KODIAQ DR2 (O'Meara+, 2017) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/161/45 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/161/45 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/161/45 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/161/45 https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/161/45 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/161/45 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/AJ/161/45/table1 (*The KODIAQ DR3 sample) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/161/45/table1? https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/161/45/table1? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/161/45/table1?
