Left: Light curves of the transits of HATS-2b observed by the astronomers involved in the ExoClock collaboration. They are plotted against the orbital phase and are compared to the best-fitting JKTEBOP and PRISM+GEMC models. The labels indicate in order: observation date, observatory, and observer. DSC stands for Deep Sky Chile, while SSO stands for Sliding Spring Observatory. Right: Residuals of each fit.
