Measuring Stellar Radial Velocity using Markov Chain Monte Carlo(MCMC) Method
Abstract
Stellar radial velocity is estimated by using template fitting and Markov Chain Monte Carlo(MCMC) methods. This method works on the LAMOST stellar spectra. The MCMC simulation generates a probability distribution of the RV. The RV error can also computed from distribution.
