It has been shown the possibility to exert a veto against spurious events measuring the longitudinal component of a signal. Numerical simulations has been performed, which take into account thermal noise between resonators and the sphere surface, for a particular configuration of the transducers.16 pages 2 ps-figures; revtex; accepted for publication in Nuovo Cimento BGeneral Relativity and Quantum CosmologyAstrophysicstext
