Period analysis results obtained by using DCDFT+ClEANest (PSD) and the JV method, for the optical data in the present work, and the combined data of the present data and the historic data, respectively. Red points labeled with names (PRi, i = 1, 2,⋯, 6 and PRhi, i = 1, 2, 3) represent the CLEANest components. Blue dashed lines represent 1 − FAP = 95%, which were calculated by using an ARI model of the noise.
