| Abstract | Aims. We present a study of the evolved stellar populations in the dwarf spheroidal galaxy Fornax based on wide-area near-infrared observations, aimed at obtaining new independent estimates of its distance and metallicity distribution. Assessing the reliability of near-infrared methods is most important in view of future spaceand ground-based deep near-infrared imaging of resolved stellar systems. Methods. We have obtained JHK imaging photometry of the stellar populations in Fornax. The observations cover an 18.5× 18.5 arcmin2 central area with a mosaic of SOFI images at the ESO NTT. Our data sample all the red giant branch (RGB) for the whole area. Deeeper observations reaching the red clump of helium-burning stars have also been obtained for a 4.5 × 4.5 arcmin2 |
