The values in parentheses are uncertainties calculated as the 1σ statistical error (from the least-squares fits to the Hα line) and the systematic error added in quadrature. Systematic errors have been estimated by the difference between Gaussian and Lorentzian fits to the lines. The epoch of the measurements are given relative to the time of SN discovery (JD 2 456 324.98).
