cds-question@unistra.frquasarsinfrared-astronomyspectroscopyline-intensitiesWe present 14 near-infrared (NIR) quasar spectra observed with the Flamingos-2 NIR spectrometer instrument at the Gemini South Observatory. The targets were selected with redshifts of (0.58~<z~<0.63) to ensure the spectral wavelength range included specifically identified hydrogen and helium broad emission lines. We present measurements of their FWHM, equivalent widths, and flux ratios relative to H{alpha}. The quasars are all within the Sloan Digital Sky Survey (SDSS) Stripe 82 region which, then also provides multi-epoch rest-frame UV and optical spectroscopic observations of our targets. In future work, these data and those from Galaxy Evolution Explorer and NUV spectra will be utilized to constrain photoionization models to determine physical conditions within the broad emission line regions, such as the incident ionizing photon flux and gas density.2019AJ....158..129Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/158/129CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/147 : The SDSS Photometric Catalogue, Release 12 (Alam+, 2015)J/ApJ/640/579 : Near-infrared spectra of 27 SDSS quasars (Glikman+, 2006)J/ApJ/753/125 : Near-IR spectroscopy follow-up of 60 SDSS-DR7 QSOshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/158/129https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/158/129http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/158/129https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/158/129https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/158/129http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/158/129GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/158/129/table1 (Summary of the observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/158/129/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/158/129/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/158/129/table1?GETtext/xml+votable180.050000true8.2144386-0.46335220.0055555555555555566/18012 18022 18067 18788 18794 19023 19027 19050 19109 19202 23187 23189 23209https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/158/129?format=asciiInfrareddefaultJ/AJ/158/129/table1Summary of the observationsrecnoRecord number assigned by the VizieR team.
