Distributions of hydrophobicity related quantities from a non-redundant subset of the PDB: Mean hydrophobicity; Root mean square hydrophobicity; Ratio between mean and root mean square hydrophobicity, τ, ratio between τ = <h>/$\sqrt{〈h^2〉}$ and $\sqrt{W_1}$ = $\sqrt{N}$<c>. All these quantities are narrowly distributed, with standard deviations of the order of less than 1/10 of the average value.
