cds-question@unistra.frsupernovaeredshiftedWe combine the CfA3 supernovae Type Ia (SN Ia) sample with samples from the literature to calculate improved constraints on the dark energy equation of state parameter, w. The CfA3 sample is added to the Union set of Kowalski et al. (2008, Cat. J/ApJ/686/749) to form the Constitution set and, combined with a baryonic acoustic oscillations (BAO) prior, produces 1+w=0.013^+0.066^_-0.068_ (0.11syst), consistent with the cosmological constant. The CfA3 addition makes the cosmologically useful sample of nearby SN Ia between 2.6 and 2.9 times larger than before, reducing the statistical uncertainty to the point where systematics play the largest role. We use four light-curve fitters to test for systematic differences: SALT, SALT2, MLCS2k2 (RV=3.1), and MLCS2k2 (RV=1.7).2009ApJ...700.1097Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/700/1097CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sn : Asiago Supernova Catalogue (Barbon et al., 1999-)J/A+A/523/A7 : Light curves of type Ia supernovae in SNLS (Guy+, 2010)J/ApJ/700/331 : CfA3: 185 type Ia SN light curves (Hicken+, 2009)J/ApJS/185/32 : First-year SDSS-II SN results (Kessler+, 2009)J/ApJ/686/749 : Improved cosmological constraints from SNe (Kowalski+, 2008)J/ApJ/673/981 : Type Ia supernova rates with HST ACS (Kuznetsova+, 2008)J/AJ/135/1598 : Optical spectroscopy of type Ia supernovae (Matheson+, 2008)J/A+A/477/717 : Spectroscopy of Type Ia supernovae (Bronder+, 2008)J/ApJ/689/377 : SNe Ia as NIR standard candles from PAIRITEL (Wood-Vasey+,J/ApJ/666/674 : ESSENCE supernova survey (Miknaitis+, 2007)J/ApJ/659/122 : Improved distances to type Ia supernovae (Jha+, 2007)J/AJ/131/527 : UBVRI light curves of 44 type Ia supernovae (Jha+, 2006)J/A+A/437/789 : Restframe I-band light curves of SN Ia (Nobili+, 2005)J/ApJ/613/200 : Hubble Higher z Supernova Search, HHZSS (Strolger+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/700/1097https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/700/1097http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/700/1097https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/700/1097https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/700/1097http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/700/1097GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/700/1097/table1 (SALT light curve fit parameters and distances.
