Distribution of the region C candidates in the Galactic XYZ coordinates, where the positive X axis points towards the Galactic centre, Y is in the direction of the Galactic rotation, and Z points towards the north Galactic pole. The candidates are represented by stars, with the colour-coding identical to that of Fig. 10. The shaded ellipses denote the areas occupied by ϵ Cha and LCC members from the BANYAN Σ model (Gagné et al. 2018). The dots indicate the mean positions of the LCC subgroups and the semi-major or minor axes of the dashed ellipses equal 2 standard deviations (Goldman et al. 2018).
