Notes. A, τrise, τfall, t0 and C are the parameters included in Eq. (1). tmax, Fmax, Δm15, Δm-10, trise and texpl are defined in Sect. 3.1 and 3.2.2. mmax is the peak apparent magnitude, Mmax the peak absolute magnitude (host-extinction corrected). The error on Mmax is about 0.15 mag, which is mainly due to the uncertainty on the distance (~7%).
