Query: Radial Dependence of Extinction in Parent Galaxies of Supernovae   The problem of extinction is the most important issue to be dealt with in the
process of obtaining true absolute magnitudes of core-collapse supernovae
(SNe). The plane-parallel model which gives absorption dependent on galaxy
inclination, widely used in the past, was shown not to describe extinction
adequately. We try to apply an alternative model which introduces radial
ependence of extinction. A certain trend of dimmer SNe with decreasing radius
from the center of a galaxy was found, for a chosen sample of stripped-envelope
SNe.
