Notes. (a) The epoch 0 is T0 in Tables A.1, A.2, and A.3, for WASP-18Ab, WASP-19b, and WASP-77Ab, respectively. (b) Number of observations. (c)Exposure time of each observation. For the variable exposure times, we consider the average during the night. (d) The RMS values were computed from the best fitted model of each light curve. (e) Light curves computed with only one reference star. (f)Light curves obtained from the Exoplanet Transit Database (ETD; https://var2.astro.cz/ETD). (g) Information not provided.
