Gravitational event search with five resonant antennas

Five cryogenic resonant gravitational antennas are now in operation. This is the first time that such a large number of high sensitive antennas are taking data and an agreement on data exchange has been signed by the responsible groups. The data exchanged will consist essentially in lists of ‘‘candidate events’’. In this paper the procedure used by the Rome group in order to obtain ‘‘candidate events’’ is presented. Some methods of analyzing the data of the “network” of the five antennas are shown.
