Histogram with the mean velocity difference (averaged over the whole wavelength range) for stars between the originally released MILES stellar library (v9.0) and the corrected version presented here (v9.1). The dispersion of the histogram (σ_ΔV) is also indicated. Offsets are also presented as a function of atmospheric parameters: effective temperature (Log(T_eff)), surface gravity (Log(g)), and metallicity ([Fe/H]).
