The distribution of φ, ψ angles for the a) (i+1), b) (i+2), c) (i+3) and d) (i+4) residues in π-HB and π-NHB turns taken together. The division of the plot into rectangular regions to enclose clusters of points and their labels are shown against (a) (but omitted from the other subfigures for clarity).
