Plots showing J0541 compared to the new UCD candidates and previously known objects listed in E. L. Martín et al. (2025). J0541 is marked as a pink rhombus, benchmark objects are marked as purple circles, and the ATMO CEQ isochrones (see M. W. Phillips et al. 2020) for the ages of 1 and 3 Myr and a distance of 403 pc are drawn. J0541 is also shown dereddened using A_V = 3 mag and R_V = 3.1. Left: CMD of I_E versus I_E − H_E. Right: color–color diagram of J_E − H_E versus Y_E − H_E. The 52 M_Jup point overlaps for the two isochrones.
