Spectra are analysed using an empirical method to \"blindly\" categorise SNe according to spectral feature strength and appearance. This method makes a clear distinction between SNe that are He-rich (IIb/Ib) and He-poor (Ic) and further analysis is performed on each subgroup. For He-rich SNe the presence of H becomes the focus. The strength, velocity, and ratio between absorption and emission of H$\\alpha$ is measured, along with additional analysis of He I lines, in order to categorise the SNe.
