Query: Preliminary study on parameter estimation accuracy of supermassive black
  hole binary inspirals for TianQin   We use the Fisher information matrix method to calculate the parameter
estimation accuracy of inspiraling supermassive black holes binaries for
TianQin, a space-borne laser interferometric detector aimed at detecting
gravitational waves in the millihertz frequency band. The `restricted'
post-Newtonian waveform in which third order post-Newtonian (3PN) phase
including spin effects (spin-orbit $\beta$ and spin-spin $\sigma$) and
first-order eccentricity contribution is employed. Monte Carlo simulations
using $10^3$ binaries for mass pairs with component masses in the range of
$({10^5},{10^7}){M_ \odot }$ and cosmological redshift $z=0.5$ show that the
medians of the root-mean-square error distributions for the chirp mass $M_c$
and symmetric mass ratio $\eta$ are in the range of $\sim 0.02\% - 0.7\% $ and
$\sim 4\% - 8\% $, respectively. The luminosity distance $D_L$ can be
determined to be $\sim 1\% - 3\% $, and the angular resolution of source
$\Delta \Omega $ is better than 12 deg$^2$. The corresponding results for
$z=1.0$ and $2.0$, which are deteriorated with the decreasing of the
signal-to-noise ratio, have also been given. We show that adding spin
parameters degrades measurement accuracy of the mass parameters (${M_c}$,
$\eta$), and the time and the orbital phase of coalescence ($t_c$, $\phi _c$);
the inclusion of the first-order eccentricity correction to the phase worsens
the estimation accuracy comparing with the circular cases. We also show the
effects of post-Newtonian order on parameter estimation accuracy by comparing
the results based on second order and third order post-Newtonian phases.
Moreover, we calculate the horizon distance of supermassive black hole binaries
for TianQin.
