cds-question@unistra.frsupernovaeinfrared-photometryvisible-astronomybroad-band-photometryWe present optical and near-infrared photometry and spectroscopy of the Type Ia SN 2003cg, which exploded in the nearby galaxy NGC 3169. The observations cover a period between 8.5 and +414d post-maximum. SN 2003cg is a normal but highly reddened Type Ia event. Its B magnitude at maximum Bmax=15.94+/-0.04 and {Delta}m15(B)_obs_=1.12+/-0.04 [{Delta}m15(B)_intrinsic_=1.25+/-0.05]. Allowing RV to become a free parameter within the Cardelli et al. (1989ApJ...345..245C) extinction law, simultaneous matches to a range of colour curves of normal SNe Ia yielded E(B-V)=1.33+/-0.11, and RV=1.80+/-0.19. While the value obtained for RV is small, such values have been invoked in the past, and may imply a grain size which is small compared with the average value for the local interstellar medium.2006MNRAS.369.1880Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/369/1880CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/369/1880https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/369/1880http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/369/1880https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/369/1880https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/369/1880http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/369/1880GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/MNRAS/369/1880/table1Original optical photometry of SN 2003cgVmag?
