Mean values and standard deviations of temperature T, magnetic field strength B, inclination γ, and vertical velocity v_z versus radial distance from the spot centre at the visible surface, τ_500nm = 1 (first column), and in two slices 160 km (second column) and 320 km (third column) below it. The values were averaged in 2.5 Mm wide sections of the radial distance. Solid lines represent the values in PGs, dashed in their surroundings. Green and red colours correspond to INW and OUT PGs, respectively. The vertical dashed lines mark the umbra-penumbra border typical for observed circular sunspots.
