Correlation diagram for the posterior density functions of all parameters for the GP analysis of the constant stars with BJD<2457700 days. The blue histogram corresponds to the complete dataset with all constant stars available. The orange histograms are the results for 80% of this dataset, and the green histogram shows this for 60% of this dataset. The dotted blue lines show the median values for the complete dataset and limit the 68.3% highest density intervals. The corresponding values are written above each parameter.
