Abstract
The SNLS experiment benefited from exceptional spectroscopic surveys, with a total of ~1500 hours of observation on 8-10m class telescopes, including the VLT with two ESO large programs. Special attention was paid to assessing the type and determining the redshift of the SN Ia candidates using a combination of SALT2 and visual inspection. This release contains: 1: a catalog of all the non SNIa objects measured in Multi Object Spectroscopy (MOS) mode during the SNLS survey 2: the SNeIa spectra observed at the Very Large Telescope (VLT) from August 1st, 2006 up to the end of the SuperNova Legacy Survey (SNLS) mid-2008. To this set, we add 8 SNeIa spectra that were acquired in MOS mode before August 1st, 2006 but that were not included in the 3-year SNLS VLT spectral sample as the extraction pipeline used for that analysis did not support MOS mode (those are SN 05D1dx, SN 05D1hm, SN 05D1if, SN 05D2le, SN 06D2ag, SN 06D4ba, SN 06D4bo and SN 06D4bw). For completeness, we further add the spectrum of SN 06D2bo, a Type Ia supernova measured in Long Slit Spectroscopy (LSS) mode in February 2006 that was initially misclassified as a non-SNIa object. In total, 70 spectra of 68 SNeIa identified as SNeIa are presented. (4 data files).
