Notes. The total extinction is reported in Col. 2, the JD of explosion in Col. 3, the bands in Col. 4, the JD of the maximum light in Col. 5, the phase of the broad maximum (in days past explosion) in Col. 6, the apparent and absolute peak magnitudes in Cols. 7 and 8 (respectively) and the 56Ni mass in Col. 9. The extinction law of Cardelli et al. (1989) was used in these estimates. The explosion epochs have been determined through a comparison with the light curves of SN 1987A.

(a)

The SN extinction is computed accounting for both Milky Way (Schlegel et al. 1998, see also Column 3 of Table 4) and host galaxy reddening components; in the case of NOOS-005, since the host galaxy is projected behind LMC, we also accounted for the contribution of LMC.

(b)

Computed using the B-band detections at days +429 and +432, and assuming the same colour evolution as SN 1987A. Using the detection at day +216, we would obtain M(56Ni)  ≈  0.35 M⊙.

(c)

Alexeyev & Alexeyeva (2008) and references therein.

(d)

The broad delayed maximum typical of 1987A-like SNe is not visible in the B band; here we report the magnitude of the pseudo-plateau visible after the early time B-band maximum.

(e)

For a comprehensive information on the multi-band light curve parameters, see Table 7 of Taddia et al. (2011).
