Conclusions

There is wide range in explosion energies, Ni masses, and ejected masses among all types of core collapse supernovae.
There is a continuum between hypernovae and ordinary supernovae.
Supernovae of both the Type I and Type II families can qualify as hypernovae (although they occur preferentially within the Ib/c class).
Not all hypernovae have detected GRBs.
The only firm SN/GRB connection is SN 1998bw, which was an extraordinary event in terms of energy and Ni production.
Both Type Ib/c and II supernovae show a correlation between energy and Ni mass, which suggests that their core physics is the same.

There is wide range in explosion energies, Ni masses, and ejected masses among all types of core collapse supernovae.
