Periodogram power peak vs. frequency from the selected peak distributions for the H band. All candidate members are shown as gray dots. (Top-left) Stars discarded owing to frequencies around 1 day^-1 are shown in blue. (Top-right) Stars discarded owing to S-statistics limit are shown in red. (Bottom-left) Stars discarded owing to RL-statistics limit are shown in yellow. (Bottom-right) Stars selected as periodic stars are shown as black empty circles. The PFA_c limit for the H band is shown as a black dashed line.
