Table 1: Summary of the parameters used in this work to describe the I-band light curve. The first five parameters are determined by fitting the data (see text for details). The next four parameters are determined from the first set and are the actual time and peak values of the light curve.
t₁ Time of the peak of the first ${\cal T}$ template

I₁ Peak magnitude of the first ${\cal T}$ template

t₂ Time of the peak of the second ${\cal T}$ template

I₂ Peak magnitude of the second ${\cal T}$ template

s_I Stretch factor of the time axis

$t_{\rm max}$ Time of the first I light curve peak

$I_{\rm max}$ First I light curve peak magnitude

$t_{\rm sec}$ Time of the second I light curve peak

$I_{\rm sec}$ Second I light curve peak magnitude
