An important feature of low-latency searches for gravitational waves is the
ability to quickly identify the sky location of possible sources. This then
allows for on the fly searches for possible electromagnetic counterparts by
pointing more conventional telescopes. Here we will discuss a method of
localizing inspiral sources using time of arrival data from both LIGO
detectors and VIRGO and how well we can expect this method to perform based
on the analysis of simulated signals. Particular focus will be placed on
how many pointings will be required for each signal and its dependence on
the signal to noise.

Notes and Changes:
preliminary draft. among the things to do are:
* add 1 & 2 sigma bars to plots
* fix plot axis lables
* normalize pointings to 1 square degree
