Notes. The volumetric supernova rates r_V are given in [10^-4 yr^-1 Mpc].

^(a)

The errors, are the 68% Poisson statistical uncertainties of the number of SNe propagated to the rates.

^(b)

The highest two redshift bins for the CC SN rates and all the SN Ia rates are upper limits with 2σ Poisson uncertainty.
