[Fe/H] for stars plotted with elliptical radius, r_ell, which is the projected semi-major axis radius, as black circles for the 312 measurements with S/N > 16 per pixel in our Sextans dSph sample. The blue line shows the binned mean and the error bars are the dispersion in each bin for the black points. The red star symbols are the nine possible members of Sextans not included in the blue mean determination, with the three with unusually low υ_los circles in black.
