RGB composite image of NGFS Tile 1, constructed using DECam filters (i′ in red, g′ in green, and u′ in blue). The field of view corresponds to a single DECam tile, with a radius of 1.1° ≈370 kpc at the distance of the Fornax cluster (D = 19.3 Mpc; Anand et al. 2024). The NIR imaging FoV is shown with an unfilled red rectangle (see Sect. 2 for details). The names of the main galaxies are indicated, with the cD galaxy NGC 1399 located near the image center. Angular and physical scales are shown: the white line in the bottom-right represents 0.25° and the line in the bottom-left corresponds to 100 kpc.
