Example of MCMC parameter chains for HARPS observations taken on November 11, 2019. The grouped columns represent the first burn-in chain (left), the second burn-in chain (middle), and the production chain (right), respectively. The left panels in each column show the sampled parameter values at each iterated step, where each colored line represent one walker and the black line represents the median of all 32 walkers. The parameter axis limits are set equal to the bounds of their uniform prior distributions (see Table 1). The right panels of each column show the ACF up to a lag of 400 steps.
