Top, left to right: final posterior distribution of the period for the first, second, and third Keplerians from the best-fitting parallel-tempered MCMC run. Bottom, left to right: final posterior distribution of the semi-amplitude for the first, second, and third Keplerians from the best-fitting parallel-tempered MCMC run. The numbers at the top of each figure correspond to the mean, variance, skewness, kurtosis, median, and mode, respectively. The solid line represents a Gaussian curve with the same mean and variance.
