Light curves from the TraMoS project of WASP-18A, WASP19 and, WASP77A during eight, nine, and nine different transits, respectively. The best-fit model from EXOFASTv2 is shown as a light blue solid line for WASP-18Ab, orange for WASP-19b, and pink for WASP-77Ab. On the right of each panel are the corresponding residuals of the model. For clarity, bothlight curves and their residuals are offset artificially. The epoch number is indicated above each light curve. Technical information about each observation is listed in Table 1.
