Distribution of all JK_s-VISTA sources with photometric uncertainties <0.1 mag (left) with a star-like morphology (top right) or a galaxy-like morphology and (J − K_s) > 1 (bottom right), over tile SMC 5_2. The left diagram shows unique sources, while the right diagrams refer to independent proper motion measurements where each source is present at least twice due to the detector overlaps. The star cluster 47 Tuc occupies about 1 / 4 of the area while the SMC star cluster NGC 121 is located north of it. The centre of the plots at (0,0) corresponds to the centre of 47 Tuc at (α₀, δ₀) = 6°.023625, −72°.081283 (J2000) and dashed lines indicate lines of constant right ascensions and declinations. Contour levels indicate stellar population densities from 20 to 500 sources in steps of 20. A dashed circle at 42′ from the centre indicates the tidal radius of the cluster while other circles correspond to distances from the centre of 20′, 40′, and 60′. The SMC stellar population increases to the south-east of it. North is at the top and east to the left.
