cds-question@unistra.frsupernovaeredshiftedphotometryWe combine high-redshift Type Ia supernovae from the first three years of the Supernova Legacy Survey (SNLS) with other supernova (SN) samples, primarily at lower redshifts, to form a high-quality joint sample of 472 SNe (123 low-z, 93 SDSS, 242 SNLS, and 14 Hubble Space Telescope). SN data alone require cosmic acceleration at >99.999% confidence, including systematic effects. For the dark energy equation of state parameter (assumed constant out to at least z=1.4) in a flat universe, we find w=-0.91^+0.16^_-0.20_(stat)^+0.07^_-0.14_(sys) from SNe only, consistent with a cosmological constant. Our fits include a correction for the recently discovered relationship between host-galaxy mass and SN absolute brightness. We pay particular attention to systematic uncertainties, characterizing them using a systematic covariance matrix that incorporates the redshift dependence of these effects, as well as the shape-luminosity and color-luminosity relationships. Unlike previous work, we include the effects of systematic terms on the empirical light-curve models. The total systematic uncertainty is dominated by calibration terms. We describe how the systematic uncertainties can be reduced with soon to be available improved nearby and intermediate-redshift samples, particularly those calibrated onto USNO/SDSS-like systems.2011ApJS..192....1Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/192/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sn : Asiago Supernova Catalogue (Barbon et al., 1999-)J/AJ/112/2408 : Light Curves of 29 SNe (Hamuy+ 1996)J/ApJ/607/665 : Type Ia supernovae at z>1 discovered by HST (Riess+, 2004)J/AJ/131/527 : UBVRI light curves of 44 type Ia supernovae (Jha+, 2006)J/A+A/477/717 : Spectroscopy of Type Ia supernovae (Bronder+, 2008)J/ApJ/673/981 : Type Ia supernova rates with HST ACS (Kuznetsova+, 2008)J/MNRAS/389/1871 : Type Ia supernovae candidates from SDSS (Horesh+, 2008)J/AJ/135/1766 : Sloan Digital Sky Survey-II supernova survey (Zheng+, 2008)J/A+A/506/999 : Photometric Calibration of SNLS (Regnault+, 2009)J/A+A/523/A7 : Light curves of type Ia supernovae in SNLS (Guy+, 2010)J/ApJS/190/418 : Light curves for 165 SNe (Ganeshalingam+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/192/1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/192/1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/192/1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/192/1https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/192/1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/192/1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/192/1/table5 (*Light-curve parameters of the combined SN sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/192/1/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/192/1/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/192/1/table5?GETtext/xml+votable180.050000true101.43125-31.231250.0055555555555555566/34 224 626 928 2227 2232 2254 2340 2347 2353 2379 2473 2608 2641 4401 4583 4684 4719 5100 6062 6877 6936 7091 7166 7522 7681 7747 7923 8341 8556 9449 9560 9698 9794 10232 10734 10767 10789 10858 11064 11181 11252 11403 11424 11425 11427 11428 11672 12103 12123 12455 13505 14907 15085 15458 16690 17152 17239 17663 17683 17686 17689 17692 17752 17753 17756 17770 17776 17811 17813 17818 17827 17831 17837 17840 17856 17857 17999 18001 18002 18010 18014 18020 18021 18022 18033 18063 18066 18072 18083 18085 18086 18091 18112 18394 18535 18686 18687 18749 18751 18769 18794 18843 18856 18882 19025 19031 19034 19035 19036 19038 19041 19043 19048 19049 19051 19052 19054 19087 19090 19091 19093 19094 19107 19108 19115 19227 19241 19456 19458 19515 19551 20090 20237 20283 20353 21857 22425 22826 23013 23102 23186 23192 23197 23203 23205 23211 23214 23828 24716 25079 25333 25521 26268 26914 27247 27256 27258 27259 27420 27491 27634 27770 27906 27910 28040 28075 28089 28249 28353 28368 28453 28498 30034 30038 30042 30044 30049 30059 30065 31628 32129 32307 32561 32569 32602 33839 34530 35629 35844 35935 36253 36805 36861 36863 37580 38613 38683 39658 39677 40906 43713 43827 43828 43855 43877 44007 45418 45500 45744 45844 45983 46394 47170 48478 48479 48500 48501https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/192/1?format=asciiOpticaldefaultJ/ApJS/192/1/table5*Light-curve parameters of the combined SN samplerecnoRecord number assigned by the VizieR team.
