V band optical light curves of V830 Tau with the flux plotted vs. rotation phase. The data points collected between BJD 58 393.742 and 58 607.363 are plotted as open green diamonds and their kernel regression vs. the rotational phase is given by the dashed green line, while the data points collected between BJD 58 765.645 and 58 916.387 are plotted as open orange triangles and their regression is given by the dot-dashed orange line. The solid red line is the regression to the whole V band photometric dataset vs. the rotation phase.
