Notes. The absolute magnitudes are corrected for MW and host galaxy extinction (Sect. 3). The magnitude 1σ uncertainties are taken from the spline fits (Sect. 4.1), with the CSS spline smoothing parameters given in the table. The total uncertainty of the rise time is estimated as the uncertainty of the rise time (Sect. 4.3) from the MC experiment and the uncertainty of the peak epoch, added in quadrature. The decline rates are determined as described in Sect. 4.2. The photometric bands are called R (Mould R), r (SDSS r) and g (SDSS g) in the table. Explosion and peak epochs are given as MJD = JD – 2 400 000.5.
