Light Curve Model Uncertainties from SDSS and SNLS Data
Abstract
We study the precision and accuracy of the SALT2 light curve model in terms of currently available data and simulations. To do this, we retrain the SALT2 model on a combined sample of SNLS3 (Guy, 2010) training sample and SDSS data. We study the impact of the changes to the model on current data as well as a simulation of DES data. By using many simulated realizations of the SDSS data that is added to the SNLS3 (Guy, 2010) sample, we compare the impact to the expected one.
