Historical and new spectral indicators from the Nearby Supernova Factory
N. Chotard1, E. Gangler1, G. Smadja1

From a sample of 58 SNe~Ia spectra obtained by the Nearby Supernova Factory with the SuperNovae Integral Field Spectrograph (SNIFS), we present measurements of spectral indicators proposed in the literature. In addition, we probe the direct correlation of spectral indicators to the Hubble diagram residuals and the relevance of such indicators as substitutes to stretch and colour.
