Transit light curves of the planet XO-2Nb collected with the Copernico (182 cm) and Schmidt 67/91 cm telescopes (Asiago Observatory) within the framework of the TASTE Project (first ten plots and the last one) and, independently, at the IAC-80 telescope (Teide Observatory, Canary Islands; remaining plots). All these observations were carried out in the Cousin/Bessell R-band. The light curves are plotted both in their original cadence (left diagrams), and binned over 2 min intervals (right diagrams). For each transit, the RMS of the residuals from the best-fit model is also tabulated. A composite light curve obtained from all the individual time series is used to determine the transit parameters shown in Table 5, as discussed in the text.
