Comparison of the true values of physical parameters with the GOG “observed” values for: top left, extinction; top right, metallicity; bottom left, surface gravity; and bottom right, effective temperature. The colour scales represent log density of objects in a bin size of: top left, 50 by 50 mmag; top right, 0.4 by 0.4 dex; bottom left, 0.5 by 0.5 dex; and bottom right, 100 by 100 K. White area represents zero stars.
