Abstract (from CDS):

We derived the distance to the central region of the Sagittarius (Sgr) dwarf spheroidal galaxy from the red giant branch tip. The obtained distance modulus is (m-M)0= 17.10±0.15, corresponding to a heliocentric distance D= 26.30±1.8Kpc. This estimate is in good agreement with the distance obtained from RR Lyrae (RR Ly) stars of the globular cluster M 54, located in the core of the Sgr galaxy, once the most accurate estimate of the cluster metallicity and the most recent calibration of the MV(RRLy) versus [Fe/H] relation are adopted.
