Abstract:

We show how, combining their outputs, at least six resonant bar antennae give with isotropic sensitivity the amplitude, polarization and direction of propagation of a burst and test for two distinctive properties of the Riemann tensor, transversality and tracelessness. If not located at the same site, to exert the two vetoes, the burst arrival times on three antennae must be known: we show how to determine them. Then in addition the propagation of the burst at light velocity is tested.
