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.
