Notes.

(*)

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).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
