Proper motion of radial velocity members of CraII (gray asterisks) and AC stars in the central field (black circles; from V20) and in the outskirts (red circles; this work). The spectroscopic members were taken from N. Caldwell et al. (2017) and S. W. Fu et al. (2019). Dotted lines indicate the CraII proper motion from G. Battaglia et al. (2022).
