# Preliminary study on parameter estimation accuracy of supermassive black hole binary inspirals for TianQin

30 May 2019 Feng Wen-Fan Wang Hai-Tian Hu Xin-Chun Hu Yi-Ming Wang Yan

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...
