Based on the color parameter {Delta}C_12_ and the decline rate {delta}m15, we found that the average absorption-to-reddening ratios for SN Ia host galaxies are R_UBVI_=4.37+/-0.25, 3.33+/-0.11, 2.30+/-0.11, and 1.18+/-0.11, which are systematically lower than the standard values in the Galaxy. We investigated the correlations of the intrinsic luminosity with light-curve decline rate, color index, and SN environmental parameters.2006ApJ...645..488Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/645/488CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/227 : The Asiago Supernova Catalogue 1999 (Barbon+, 1999)II/256 : Sternberg Supernova Catalogue, 2004 version (Tsvetkov+, 2004)J/A+A/317/423 : Revised photometry of SNIa (Patat, 1997)J/AJ/112/2408 : Light Curves of 29 SNe (Hamuy+ 1996)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)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/645/488https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/645/488http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/645/488https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/645/488https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/645/488http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/645/488GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/ApJ/645/488/table1Parameters of well-observed nearby SNe Iae_E(B-V)12? rms uncertainty on E(B-V)12magstat.errorfloatnullableE(B-V)hAdopted reddening in the host galaxymagphot.color.excessfloatrecnoRecord number assigned by the VizieR team.
