Abstract:
We present deep wide-field VI CCD photometry of the Sextans dwarf
spheroidal galaxy (dSph) in the Local Group, covering a field of
42'x28' located at the center of the galaxy (supplemented by short B
photometry). The limiting magnitudes with 50% completeness are
V=24.4mag and I=23.6mag.
Description:
BVI CCD images of the Sextans dSph were obtained at the 3.6m
Canada-France-Hawaii Telescope (CFHT) on the nights of UT 2001
February 16-17 using the CFH12K mosaic CCD camera.
