The EFF Segregated model. Top panel: density of candidate members (black dots with Poisson uncertainties) together with: the best-fitting model (computed from the semi-major and semi-minor axes of the core radius and plotted in dotted and dashed red lines, respectively) and samples from the posterior distribution (grey lines). Bottom panel: galactic coordinates of our candidate members (red stars), and those of Cantat-Gaudin et al. (2018a, white circles). Also plotted is the core radius (black ellipse) and two perpendicular (black) lines extending ten core radius units in the directions of the semi-major and semi-minor axes.
