$^{a}$  A distance modulus~$\mu$~=~29.84 $\pm$ 0.16 mag and a colour excess $E(B-V)~=~0.092$~mag were adopted. 
$^b$  The uncertainty in the epoch of maximum is defined as the time period in which the magnitude is not more than 0.01 mag fainter than the peak magnitude \citep{Yoshii03}. 
$^{c}$  Epoch with respect to the estimated $B$-band maximum JD~2~454~337.0 $\pm$ 1.0. 
$^{d}$  Epoch with respect to the estimated explosion date JD~2~454~325.5 $\pm$ 2.5. 
$^{e}$~Decline rates (mag d$^{-1}$) were estimated using linear least-square fitting.
