Distances measured using Type Ia supernovae (SNIa) are an excellent way of constraining the equation of state of the dark energy. However, the brightnesses of these SNIa have variabilities due to internal mechanisms or environmental effects that have to be accounted for. Empirical models of the SNIa spectral energy distribution can be employed to standardize these objects. One of the most efficient of such models is the Spectral Adaptative Light-curve Template 2 (SALT2) developed by Guy et al. (2007). This model uses a standardization based on stretch and color, which are the best known sources of variability in SNIa. A new model called SUpernova Generator And Reconstructor (SUGAR) was proposed by Léget et al. (2020), who showed with the h...
