Notes. The resolution of each spectrum was estimated from [O I] sky lines. Rest frame phases refer to the estimated epoch of the explosion. NOT: 2.56 m Nordic Optical Telescope with ALFOSC; VLT: 8 m Very Large Telescope with X-shooter (ESO Observatorio del Paranal, Chile); KECK: 10 m Keck I telescope with LRIS (Mauna Kea Observatory, Hawaii, USA). Data will be released through WISEREP.
