Period analysis of the RVs using the Stellingwerf statistics. Top panel: RVs plotted in phase with a period of 282 d. Bottom panel: Stellingwerf 1 − θ statistical indicator for a sine signal of period 282 d sampled the same way as HD 39853. Middle bottom panel: same as bottom for the 282 d sine signal (red curve) and for the HD 39853 data (black curve). Middle top panel: the difference between the red and black curve of the previous panel, showing possible residual signals (here one around 110 d).
