Left: image of about 4′ in diameter in the g band centred on KMHK 1762. The red circle indicates the SC radius of 0.5′. Right: PMs of the 12 stars of KMHK 1762 with astrometric data from Gaia EDR3. The red crosses are the stars with PMs compatible with the cluster within their uncertainties. The empty red square indicates a star likely with statistically compatible PMs, but with large uncertainties (see text). Blue circles are stars with measured PMs beyond 5σ from the weighted mean SC PM. Grey points represent all stars within 10′ from the cluster centre, without their uncertainties to preserve the readability of the figure.
