supernova

Caption: Gaussian Process (GP) fit of the multi-colour light curves of SN 03D1au. A Matérn-5/2 kernel was used in this case. The solid lines show the mean of the GP fits while the shaded areas represent one standard deviation (1-$\sigma$).

Caption: Flowchart of the main procedures in PISCOLA. Gaussian Process is used to fit the light curves of SNe Ia. Afterwards, an SED template is warped to match the observed SN colors, which is then corrected for redshift (K-correction) and Milky Way dust extinction.
