Notes. Errors are quoted as the 16th and 84th percentiles of the post-burnin MCMC posteriors. It is worth mentioning that the reported errors on these parameters do not include systematic errors, such as period error, black body modelling, and flux calibration. The results from the corner plot should be interpreted with due consideration.
