Descripción
We present accurate B, V, R photometry of the Sculptor dwarf spheroidal
galaxy. The data have been collected with the Wide Field Imager
available at 2.2 m ESO/MPI telescope and cover an area of about
100×40 arcmin2 around the Sculptor center. The final
catalogue includes 100,000 stars. We found that blue and red Horizontal
Branch stars present different radial distributions. This finding
supports previous results. Moreover, we present a preliminary comparison
between theoretical predictions for H and He burning phases and
observational data.
