We estimated the $M_g$ absolute magnitudes for the same stars via the re-reduced Hipparcos parallaxes and calibrated the absolute magnitude offsets, $\\Delta M_g$, relative to the intrinsic sequence of Hyades to a third order polynomial in terms of $\\delta_{0.41}$. The ranges of the calibrations are $-2<$[Fe/H]$\\leq$0.3 dex and $4<M_g\\leq6$ mag.
