We present an update of our previous study [2] on how v oscillations affect the signal from a supernova core collapse observed in the LVD detector at LNGS.In this paper we use a recent,more precise determination of the cross section [8] to calculate the expected number of inverse beta decay events,we introduce in the simulation also the v-Fe interactions,we include the Earth matter effects and,finally,we study also the inverted mass hierarchy case.
