This paper also uses data obtained at the South African Astronomical Observatory (SAAO). Some observations were taken with the Southern African Large Telescope (SALT) as part of proposal ID 2012-1-RU-005 (PI: Jha). Some of the data presented herein were obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California, and NASA; the observatory was made possible by the generous financial support of the W.M. Keck Foundation. Based in part on observations made with the Nordic Optical Telescope, operated on the island of La Palma jointly by Denmark, Finland, Iceland, Norway, and Sweden, in the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofisica de Canarias. For their excellent assistance, we are grateful to the staffs of the many observatories where we collected data.This research has made prodigious use of the NASA/IPAC Extragalactic Database (NED), which is operated by the Jet Propulsion Laboratory, California Institute of Technology, under contract with NASA. It has also made use of NASA's Astrophysics Data System (ADS), the CfA Supernova Archive (funded in part by NSF grant AST-0907903), and the Central Bureau for Astronomical Telegrams (CBAT) list of SNe (http://www.cbat.eps.harvard.edu/lists/Supernovae.html).
