Query: Gravitational waves from inspiralling compact binaries: Parameter
  estimation using second-post-Newtonian waveforms   The parameters of inspiralling compact binaries can be estimated using
matched filtering of gravitational-waveform templates against the output of
laser-interferometric gravitational-wave detectors. Using a recently calculated
formula, accurate to second post-Newtonian (2PN) order [order $(v/c)^4$, where
$v$ is the orbital velocity], for the frequency sweep ($dF/dt$) induced by
gravitational radiation damping, we study the statistical errors in the
determination of such source parameters as the ``chirp mass'' $\cal M$, reduced
mass $\mu$, and spin parameters $\beta$ and $\sigma$ (related to spin-orbit and
spin-spin effects, respectively). We find that previous results using template
phasing accurate to 1.5PN order actually underestimated the errors in $\cal M$,
$\mu$, and $\beta$. For two inspiralling neutron stars, the measurement errors
increase by less than 16 percent.
