... The nebular sp ectra of SNeIa can b e used to determine the mass, density, and distribution of the SN ejecta, and the distance and reddening to the SN. ... The synthetic sp ectra are then corrected for the distance and reddening to the observed SN, and compared to the observed sp ectrum. ... If we assume that we know from explosion models the mass ejected with velocities b elow the observed value, then an estimate of the most likely values of distance and filling factor can b e derived (Figure 2). ...
