Comparative Ks × (J − Ks) colour-magnitude diagrams. Top: CASU aperture photometry for stellar sources (flag −1) for the entire e1084 tile (left), for the region of the Carina Nebula shown in Fig. 7 (centre) and for the stellar cluster NGC 3324 (right panel, 6 arcmin radius area). The sharp end at Ks = 17.9 is caused by the stellar flag criterion applied. Bottom: the CMD for the same areas in the top using PSF photometry. In the CMDs for the entire tile, the narrow and vertical structure seen at (J − Ks) ~ 0.9 is the sequence of unreddened nearby M dwarfs (e.g. Alonso-García et al. 2018; Mejías et al. 2022).
