SALT2: Using distant supernovae to improve the use of type la supernovae as distance indicators

Aims. We present an empirical model of type la supernovae spectro-photometric evolution with time. Methods. The model is built using a large data set including light-curves and spectra of both nearby and distant supernovae, the latter being observed by the SNLS collaboration. We derive the average s...
