Effects of systematic shifts in the spectroscopically observed stellar parameters T_eff (left), [Z/H] (middle) and log g (right panels) on our determined distances. For this exercise, we again use the simulated PARSEC sample with high-resolution-like observational errors and the full input parameter set (set 1: x = {[M/H] ,T_eff,log g,m,colours}). In each panel, the errorbars show the mean and standard deviation of the relative distance errors, as a function of the value of a fixed shift in the particular stellar parameter. Dwarfs (log g> 4) and giants are shown separately in the top and bottom rows, respectively.
