Notes. For SN 1998bu at 269 days the temperature and density are not fitted (see text for details). (a) Days after the explosion, assuming a rise time of ~18 days (Ganeshalingam et al. 2011). (b)Doppler full width at half maximum. (c)Shift velocity. (d)Mean and standard deviation over all fit samples. For shift velocities we calculated the mean and standard deviation of the absolute values.
