Simulation tool of a Supernova search with VST

To improve the estimate of SN rates for all types as a function of redshift has been proposed and accepted a three years SN search with the VST telescope. To help planning an optimal strategy for the search, we have developed a simulation tool used to predict the numbers of Supernovae of different types which are expected to be discovered in a magnitude-limited survey. In our simulation a most important ingredient has been the determination of the K-correction as function of redshift for every SN types and filters set. We estimate to discover about 300 SNe in the course of this search. This number, above a given threshold, is constant even if the frequency of observation increases. Moreover we find that to high redshift the infrared band become more important.
