Parameter estimation of spinning binary inspirals using Markov chain Monte Carlo

We present a Markov chain Monte Carlo (MCMC) technique to study the source parameters of gravitational-wave signals from the inspirals of stellarmass compact binaries detected with ground-based gravitational-wave detectors such as LIGO and Virgo, for the case where spin is present in the more massive compact object in the binary. We discuss the aspects of the MCMC algorithm that allowus to sample the parameter space in an efficientway. We show sample runs that illustrate the possibilities of our MCMC code and the difficulties that we encounter.
