Notes. The maximum likelihood solution, median, mode, and standard-deviation of the posterior distribution for each parameter are shown, as well as the 68.27%, 95.45%, and 99.73% confidence intervals. The prior for each parameter can be of type: : uniform, : normal, or : truncated normal. Reference epoch: 2455500.0 BJD.
