Notes. The phase (day) has been corrected for time dilation (z = 0.256) and relative to the SN r-band maximum on MJD 56 697. Resolution of NTT + EFOSC2 is adopted from Smartt et al. (2015), as measured from the sky lines. For VLT + FORS2 with a filter GG435+81 and a 1.̋0 slit, the resolving power is 440 at the central wavelength 5900 Å, and the dispersion is 3.27 Å/pixel.
