cds-question@unistra.frsupernovaeredshiftedWe present 139 spectra of 124 Type Ia supernovae (SNe Ia) that were observed at the ESO/VLT during the first three years of the Canada-France-Hawai Telescope (CFHT) supernova legacy survey (SNLS). This homogeneous data set is used to test for redshift evolution of SN Ia spectra, and will be used in the SNLS 3rd year cosmological analyses. Spectra have been reduced and extracted with a dedicated pipeline that uses photometric information from deep CFHT legacy survey (CFHT-LS) reference images to trace, at sub-pixel accuracy, the position of the supernova on the spectrogram as a function of wavelength. It also separates the supernova and its host light in ~60% of cases. The identification of the supernova candidates is performed using a spectrophotometric SN Ia model.2009A&A...507...85Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/507/85CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/317/423 : Revised photometry of SNIa (Patat, 1997)J/ApJ/607/665 : Type Ia supernovae at z>1 discovered by HST (Riess+, 2004)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 & low redshifts (Blondin+, 2006)J/ApJ/645/488 : SN type Ia luminosities (Wang+, 2006)J/AJ/133/403 : Light curve of 11 type Ia supernovae (Garg+, 2007)J/ApJ/659/122 : Improved distances to type Ia supernovae (Jha+, 2007)J/A+A/477/717 : Spectroscopy of Type Ia supernovae (Bronder+, 2008)J/MNRAS/389/1871 : Type Ia supernovae candidates from SDSS (Horesh+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/507/85https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/507/85http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/507/85https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/507/85https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/507/85http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/507/85GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/507/85/table1 (*List of SNLS 3rd year ESO-VLT SN Ia and SN Ia* spectra)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/507/85/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/507/85/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/507/85/table1?GETtext/xml+votable180.050000true36.811125-4.31798330.0055555555555555566/17683 17686 17689 17692 27247 27256 27258-27259 48478-48479 48500-485012.381800341673347e-19 2.821731604724377e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/507/85?format=asciiOpticaldefaultJ/A+A/507/85/table2Results of identifications of the SNLS 3rd year ESO-VLT SN Ia and SN Ia* spectrazRedshift (of SN or host)src.redshiftfloate_zrms uncertainty on zstat.error;src.redshiftfloatrecnoRecord number assigned by the VizieR team.
