Abstract
The SN Ia samples in this paper come from the following surveys: SuperNova Legacy Survey (SNLS): The SNLS was conducted between 2002 and 2008 with the 3.6m Canada-France-Hawaii Telescope located atop the summit of Mauna Kea on the island of Hawai'i. The instrument MegaCam was used to image four one-square degree fields located in areas of low galactic extinction in the gM, rM, iM, and zM bands. For spectroscopic confirmation, several 8-10m telescopes were used, including the Gemini North and South telescopes, the Very Large Telescope, and the Keck telescopes. SN spectra have been published in several papers. SDSS-II SN Survey: The SDSS-II SN survey used the 2.5m SDSS telescope located at the Apache Point Observatory in New Mexico. In this program, a part of the sky called stripe 82 was repeatedly scanned in the ugriz bands for SNe during the northern falls of 2005, 2006, and 2007. Visual inspection and model fitting of the light-curves were performed to select SN Ia candidates, which were then spectroscopically confirmed using a number of telescopes. Carnegie Supernova Project (CSP): CSP was conducted between 2004 and 2009 (Hamuy+ 2006PASP..118....2H) at the Las Campanas Observatory in Chile using several telescopes, most notably the 1m Swope and 2.5m du Pont telescopes. CSP has obtained light-curves in the u'gir'i'BVYJHKs bands, which range from the near-UV to the near-infrared (near-IR). Centre for Astrophysics (CfA) Supernova Survey: Astronomers at the Harvard-Smithsonian CfA have been collecting photometric and spectroscopic data of local SNe Ia since 1993. The CfA SN program uses the 1.2m telescope at the Fred Lawrence Whipple observatory using the UBVIr'i' bands. See section 2 for further details. (2 data files).
