Query: Localization of transient gravitational wave sources: beyond
  triangulation   Rapid, accurate localization of gravitational wave transient events has
proved critical to successful electromagnetic followup. In previous papers we
have shown that localization estimates can be obtained through triangulation
based on timing information at the detector sites. In practice, detailed
parameter estimation routines use additional information and provide better
localization than is possible based on timing information alone. In this paper,
we extend the timing based localization approximation to incorporate
consistency of observed signals with two gravitational wave polarizations, and
an astrophysically motivated distribution of sources. Both of these provide
significant improvements to source localization, allowing many sources to be
restricted to a single sky region, with an area 40% smaller than predicted by
timing information alone. Furthermore, we show that the vast majority of
sources will be reconstructed to be circularly polarized or, equivalently,
indistinguishable from face-on.
