Synthetic light curve SYNTH-2a (blue dots), with the derived best-fit model (red line) and the original light curve model (green line). This synthetic light curve shows a starspot crossing at the limb of the star around phase −0.01. The obtained photometric properties and spot parameters can be found in Tables B.1 and B.3. The (O−C) residuals and the difference between the original and best-fit TLC models are shown in Fig. A.2.
