Abstract:
This is the second paper of a series in which we present new
measurements of the observed rates of supernovae (SNe) in the local
Universe, determined from the Lick Observatory Supernova Search
(LOSS). In this paper, a complete SN sample is constructed, and the
observed (uncorrected for host-galaxy extinction) luminosity functions
(LFs) of SNe are derived. These LFs solve two issues that have plagued
previous rate calculations for nearby SNe: the luminosity distribution
of SNe and the host-galaxy extinction. We select a volume-limited
sample of 175 SNe, collect photometry for every object and fit a
family of light curves to constrain the peak magnitudes and
light-curve shapes. The volume-limited LFs show that they are not well
represented by a Gaussian distribution.
