SUGAR: An Improved Empirical Model of Type Ia Supernovae based on Spectral Features

---

SUGAR is a spectro-temporal model for Type Ia supernovae trained on the spectrophotometric time series obtained by the Nearby Supernova Factory. The training procedure and results are described in Leget et al. 2020. The spectral time series used for the training and validation are available at here.
