Fig. 4


Distribution of all stars in the MUSE sample in the radial velocity vs. metallicity plane, colour-coded using their membership probabilities. Membership probabilities were determined using the EM technique as described in the text. For the cluster population, the mean radial velocity and metallicity plus their intrinsic dispersions are indicated with the grey square. The bulk of orange coloured member stars does not hide any non-member stars.
