Table 1: Summary of the error budget for the $EW_{w}\{{\rm Si}~{\rm II}\}$ measurements.
Table 2: List of nearby SNe used in this work.
Table 3: SALT2 estimates and $EW_{w}\{{\rm Si}~{\rm II}\}$ results for nearby SNe. The blank spaces `` $\cdots$ '' in $EW_{w}\{{\rm Si}~{\rm II}\}$ column indicate insufficient presence of Si II feature despite an adequate wavelength coverage.
