Abstract:
We create new U-, B-, V-, R- and I-band light-curve templates of Type
Ia supernovae (SNe Ia) and re-analyse 122 nearby (redshift <0.11) SNe
Ia using a new 'Multiband Stretch method', which is a revised Stretch
method extended to five bands.
Description:
We use U-, B-, V-, R- and I-band light curves in the Vega system of
122 SNe in this work. All of the sample have B- and V-band photometry,
but they do not always have U-, R- and I-band photometry.
