SNe do not change significantly when the observation interval is shorter thanġ0 days. Intervals, and find that the LFs are enhanced at the high-luminosity end andĪppear more "standard" with smaller scatter, and that the LFs and fractions of SN subclasses in a magnitude-limited survey with different observation

Furthermore, we derive the LFs and the observed fractions of different

Significant fractions of SNe II-L (10%), IIb (12%), and IIn (9%) in the SN II We derive the observedįractions for the different subclasses in a complete SN sample, and find There are notable differences in the LFs for galaxies ofĭifferent Hubble types (especially for SNe Ia). The volume-limited LFs show that they are not well represented by a Volume-limited sample of 175 SNe, collect photometry for every object, and fitĪ family of light curves to constrain the peak magnitudes and light-curve Luminosity distribution of SNe and the host-galaxy extinction. Issues that have plagued previous rate calculations for nearby SNe: the

Sample is constructed, and the observed (uncorrected for host-galaxyĮxtinction) luminosity functions (LFs) of SNe are derived. The Lick Observatory Supernova Search (LOSS). The observed rates of supernovae (SNe) in the local Universe, determined from
