Description
We present expected fast sky localisation of coalescing binaries with a hierarchical search using three gravitational wave (GW) detectors, HLV (Hanford/Livingston/Virgo).
A hierarchical search can be used with different sensitivity GW detectors, and is aimed at making effective use of the least sensitive detector’s information. In the hierarchical network, the less sensitive detectors are included into the network with a lower SNR threshold than the higher sensitivity detectors, only when a coincidence trigger is detected by the sub network of higher sensitivity detectors.
Here we demonstrated the sky localisation using a hierarchical search using the two higher sensitivity LIGO detectors and the less sensitive Virgo detector, using simulated signals.
