Color-color diagram used to distinguish stars and galaxies. The black dashed rectangle indicates our selection of lens candidates (J − W1 > −0.35, g − i > 0.4), while stars are located in the J − W1 ≲ −0.5 region (in AB system, extinction-corrected magnitudes). Photometric redshifts derived from SED analysis are shown as a color map, as additional redshift constraints were applied to exclude sources with unreliable photometric redshifts, particularly at z < 0.1 and z > 0.6. Best candidates (A lenses) were further selected based on the χ_r² of the models and the proximity of the submillimeter sources.
