text: Furthermore, we measure the proper motion of the system (μ _{α } = 5.19(22) and μ _{δ } = -0.56(25) mas yr^{-1}), which is not only important for analysing its motion in the cluster, but is also essential for a proper interpretation of γ, given the latter parameter's correlation with the variation of the projected semimajor axis.
