KMOS object proper motions and CMD, and cluster simulation. The triangles represent Can1, and the blue circles represent the remaining objects in the field. Left: vector-point diagram. Middle: CMD. The vertical dashed line marks the color-cut we made to exclude foreground stars (H − Ks  =  1.3). The horizontal dashed line marks the magnitude cut we made to exclude stars with low spectroscopic S/R (Ks  =  14.5). Right: Spisea cluster simulation. The blue crosses represent members of a simulated cluster. The legend box displays the main features of the cluster. The shaded area represents the uncertainty in the position in the CMD for the members of the simulated cluster due to variations in extinction.
