cds-question@unistra.frsupernovaeredshiftedWe present the results of spectroscopic observations from the ESSENCE high-redshift supernova (SN) survey during its first four years of operation. This sample includes spectra of all SNe Ia whose light curves were presented by Miknaitis et al. (2007, Cat. J/ApJ/666/674) and used in the cosmological analyses of Davis et al. (2007ApJ...666..716D) and Wood-Vasey et al. (2007ApJ...666..694W). The sample represents 273hr of spectroscopic observations with 6.5-10m class telescopes of objects detected and selected for spectroscopy by the ESSENCE team. We present 184 spectra of 156 objects. Combining this sample with that of Matheson et al. (2008, Cat. J/AJ/135/1598), we have a total sample of 329 spectra of 274 objects. From this, we are able to spectroscopically classify 118 Type Ia SNe.2009AJ....137.3731Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/137/3731CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.ctio.noao.edu/essence/ : ESSENCE pageJ/ApJ/666/674 : ESSENCE supernova survey (Miknaitis+, 2007)J/AJ/135/1598 : Optical spectroscopy of type Ia supernovae (Matheson+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/137/3731https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/137/3731http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/137/3731https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/137/3731https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/137/3731http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/137/3731GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/137/3731/table1 (ESSENCE spectroscopic targets)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/137/3731/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/137/3731/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/137/3731/table1?GETtext/xml+votable180.050000true5/4425 6/17251 17295 17316 17318 17319 17321 17324 17325 17326 17668 17699 17709 17714 17999 18008 18010 18011 18032 18033 18075 36774 36775 36779 36780 36781 36783 36786 36792 36794https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/137/3731?format=asciiOpticaldefaultJ/AJ/137/3731/table1ESSENCE spectroscopic targetsrecnoRecord number assigned by the VizieR team.
