Abstract (from CDS):

We present V and I photometry of a 9.4x9.4arcmin2 field centred on the dwarf spheroidal galaxy Leo I. The I magnitude of the tip of the red giant branch (RGB) is robustly estimated from two different data sets (ITRGB= 17.97+0.05–0.03). From this estimate, adopting [M/H]≃-1.2 from the comparison of RGB stars with Galactic templates, we obtain a distance modulus (m-M)0= 22.02±0.13, corresponding to a distance D= 254+16–19kpc.
