\tablefoot {Errors on all magnitudes have been determined by taking into account the uncertainty of PSF fitting of the SN, the uncertainty of having accurately removed the background contamination measured via artificial-star experiments and the uncertainty of both calculating the colour-terms and zero-points of each night's imaging via the measurement of a local standard stars in the field of the~SN. \\
