Based on the rad and logg, the derived grave_mass does not match the given value.

I reviewed the output of certain stellar parameters in the best_fit_average.dat file, which provided the median, upper, lower, 3sig_low, and 3sig_up values for logg, rad, and grav_mass. For example, the median values are logg=4.4723, rad=0.7974, and grav_mass=0.3833. Using the formula (\log g = \log M - 2 \log R + 4.437) and substituting logg and rad, I calculated grav_mass = 0.69, which does not match the given value of 0.3833.

I am not sure why they do not match. Could you please explain the main reason for this discrepancy? Thank you.
