Query: Estimating parameters of coalescing compact binaries with a detector
  network including LIGO Australia   One of the goals of gravitational-wave astronomy is simultaneous detection of
gravitational-wave signals from merging compact-object binaries and the
electromagnetic transients from these mergers. With the next generation of
advanced ground-based gravitational wave detectors under construction, we
examine the benefits of the proposed extension of the detector network to
include a fourth site in Australia in addition to the network of Hanford,
Livingston and Cascina sites. Using Bayesian parameter-estimation analyses of
simulated gravitational-wave signals from a range of coalescing-binary
locations and orientations, we study the improvement in parameter estimation.
We find that an Australian detector can break degeneracies in several
parameters; in particular, the localization of the source on the sky is
improved by a factor of ~4, with more modest improvements in distance and
binary inclination estimates. This enhanced ability to localize sources on the
sky will be crucial in any search for electromagnetic counterparts to detected
gravitational-wave signals.
