Notes. For our spectroscopy, we used the Double Spectrograph (DBSP) on the 5 m telescope (P200) at Palomar Observatory, the Dual Imaging spectrograph (DIS) on the Astrophysical Research Consortium 3.5 m telescope at Apache Point Observatory (APO; New Mexico, USA), the Andalucia Faint Object Spectrograph and Camera (ALFOSC) on the 2.5 m Nordic Optical Telescope (NOT) at the Roque de los Muchachos observatory (La Palma, Spain), the DEep Imaging Multi-Object Spectrograph (DEIMOS) on the 10 m Keck 2 telescope at the W. M. Keck Observatory (Hawaii, USA), and the Low Resolution ImagingSpectrometer (LRIS) on the 10 m Keck 1 telescope. The resolution of the spectra were measured using the [O iii] λ4959 line (or, when resolved, the [S ii] λ6717, 6731 lines) of the host galaxy. The epoch of the measurements are given relative to the time of SN discovery (JD 2 456 324.98).
