Left: (Z−J, Z) colour–magnitude diagram for 6.5 deg² in the central region of USco (Lodieu et al. 2007). The USco cluster sequence is well separated from field stars. Right: vector point diagram. We averaged the values of the proper motion in each direction from the datasets listed in Table 1, where the error bars represent the dispersion between each catalogue. The mean proper motion of the association is (μ_αcosδ,μ_δ) ~ (−11, −25) mas/yr. Our transiting system is highlighted with a large red dot, demonstrating its photometric and astrometric membership.
