Notes. First column: TDEs for which a time lag between Hα and continuum is measurable. TDEs for which the light curve peak has not been observed are indicated with an asterisk, and in these cases the tabulated Hα and He I is a lower limit. If the TDE shows N III Bowen lines we note it in a parenthesis next to their name. Second column: Lag between peak He I luminosity and the optical light curve peak. If the line does not peak we show the upper-limit. Third column: Lag between peak Hα luminosity and the optical light curve peak. Fourth column: Deduced distances extracted from equation: rlag, Hα = τlag, Hα c (see Sect. 6.1) where τlag, Hα = tpeak, Hα − tpeak, LC. Fifth column: The blackbody radius value at peak for each TDE (see Table B.1).
