CPS results of M, A, P and φ_min for HD 1405, HD 10008, HD 26923, and HD 29697. For M, A, and P the results from the independent datasets are shown with the black squares with error bars while results from the rest of the datasets are shown with points. Datasets with a constant brightness model (K = 0) are shown with A set to 0. The light curve minimum phases φ_min phased with P_al are shown in the fourth panel with black squares denoting the primary minima and grey triangles the secondary minima. This panel is shaded grey if the candidate P_al does not have a significant Kuiper statistic. The mean photometric period P_w is shown in the third panel as a solid line and the active longitude period P_al with the dashed line. We note that the error bars are often smaller than the plot symbols.
