Top left: Color-magnitude diagram of OC CWNU 2672 members from Hunt & Reffert (2023) with the HMXB IGR J16465-4507 marked by a black dot. Here and in the subsequent plots, the color encodes the probability of OC membership. A MIST isochrone or a set of MIST isochrones (Dotter 2016; Choi et al. 2016) corresponding to the OC age (as discussed in the text) are plotted. These are shifted in the visual magnitude space using the distances from Hunt & Reffert (2023) and extinctions in Cavallo et al. (2024). Solar metallicity is assumed. Top right: Parallax distribution of OC members with the parallax of the HMXB marked by a vertical black line. Bottom left: Position diagram of the OC members and HMXB in the equatorial coordinate system. The median RA and Dec of the OC members are marked by dotted black lines. Bottom right: Vector-point diagram (VPD) of the OC members and HMXB. The median μ_RA and μ_Dec are marked by dotted black lines.
