Selected spectra (data from Sako et al. 2014) for 19 SDSS SNe Ib/c (SN 2007gl was classified by Baltay et al. 2007). The vertical dashed lines indicate the rest wavelengths of He iλλ5876, 6678, 7065, and Si iiλ6355 at zero velocity. The epoch of each spectrum is marked in Fig. 4 with a vertical red segment. Most of the spectra show narrow emission lines from the host galaxy.

Lefthand panel: r-band cadence distribution for the SDSS SN Ib/c sample. Typical values are between 4 and 5 days. Righthand panel: r-band follow-up distribution for the SDSS SN Ib/c sample. SNe were followed for a minimum of ~10 days to a maximum of ~90 days after discovery.
