cds-question@unistra.frsupernovaephotometryline-intensitiesWe present a quantitative study of a new data set of high redshift Type Ia supernovae spectra, observed at the Gemini telescopes during the first 34 months of the Supernova Legacy Survey. During this time 123 supernovae candidates were observed, of which 87 have been identified as SNe Ia at a median redshift of z=0.720. Spectra from the entire second year of the survey and part of the third year (59 total SNe candidates with 46 confirmed SNe Ia) are published here for the first time. The spectroscopic measurements made on this data set are used determine if these distant SNe comprise a population similar to those observed locally. Rest-frame equivalent width and ejection velocity measurements are made on four spectroscopic features. Corresponding measurements are presented for a set of 167 spectra from 24 low-z SNe Ia from the literature.2008A&A...477..717Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/477/717CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sn : Asiago Supernova CatalogueII/189 : Magnitude Observations of Type I Supernovae (Cadonau+ 1990)J/AJ/112/2408 : Light Curves of 29 SNe (Hamuy+ 1996)J/A+A/437/789 : Restframe I-band light curves of SN Ia (Nobili+, 2005)J/AJ/131/527 : UBVRI light curves of 44 type Ia supernovae (Jha+, 2006)J/AJ/131/1648 : Type Ia supernovae at high and low redshifts (Blondin+, 2006)J/ApJ/645/488 : SN type Ia luminosities (Wang+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/477/717https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/477/717http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/477/717https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/477/717https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/477/717http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/477/717GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/477/717/table6 (Observed properties and instrument settings for SNLS SNe candidates observed from November 2004 to May 2006)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/477/717/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/477/717/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/477/717/table6?GETtext/xml+votable180.050000true36.8684875-4.744919440.0055555555555555566/11403 11424-11425 11427-11428 17686 17689 17692 27256 27258 48478-48479 48500-48501https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/477/717?format=asciiOpticaldefaultJ/A+A/477/717/table6Observed properties and instrument settings for SNLS SNe candidates observed from November 2004 to May 2006SNLSSN namemeta.id;meta.maincharprimaryRAJ2000Right ascension (J2000)pos.eq.ra;meta.mainObsDateObservation datetime.epoch;obsnullableExpTimeExposure timestime.duration;obs.exposureintModeObserving mode (1)meta.code;obscharDEJ2000Declination (J2000)pos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
