Transits from the DK telescope. Left panel: light curves of 11 transits (10 complete and one partial) of HATS-2 b observed with the Danish 1.54 m telescope, shown in chronological order. They are plotted against the orbital phase and are compared to the best-fitting models. Labels indicate the observation date and the filter (Bessell I and R) that was used for each data set. Starspot anomalies are visible in all the light curves. Right-hand panel: the residuals of each fit.
