Distribution of Supernovae according to their parent galaxies' recession velocity.

This graph shows the distribution of SNe according to the recession velocity of their parent galaxies. This graph is kept up to date till SN 2000ek Along X-axis there are all velocity bands so that you have to read in this way: for example, the band on the graph marked as 2000 takes in all parent galaxies' recession velocities faster than 1000 until 2000 Km/sec.
