Strömgren photometric metallicity maps of RGB (left) and supergiant (right) stars of the Clouds derived from the Gaia DR3–XP spectra. Each spatial bin corresponds to 0.25 deg2 and 0.5 deg2 for the RGB and supergiant stars, respectively. The maps are centred at RA = 81.24 deg and Dec = −69.73 deg; (van der Marel & Cioni 2001). The bar regions of both galaxies are marked with black ellipses. The colour-coding from blue to white shows the increasing median metallicity values. We note the larger relative difference between the LMC and SMC metallicity in the supergiants than in the RGB stars. The distribution of RGB stars, which contains fainter sources than that of supergiants, at the core of the galaxies may be affected by a lack of sources due to crowding.
