The zero-point constant values for the BCV scale from the sample spectra containing 128 stars. Error bars are the propagated errors from the observational uncertainties. Horizontal lines mark the values of the weighted mean: C2 = 2.3653 if the Sλ(V) function of M. S. Bessell (1990) is used and C2 = 2.3826 if the Sλ(V) function of A. U. Landolt (1992) is used.
