Positions and color–magnitude distribution of stars in our sample. Left panel: positions of all stars with PM measurements in this work (orange squares) and PM vectors for stars with large PMs. Middle panel: (F775W–F850LP) vs. F775W color–magnitude diagram from the HST/ACS photometry of Robberto et al. (2013). Previously identified members BN and source x are omitted, as they are not detected at optical wavelengths. Right panel: same as the middle panel but for (F555W–F850LP) vs. F555W. The star marked as a green diamond in the left panel is omitted, as it is not detected at F555W.
