Dependencies between scaling factors. Dependencies between scaling factors. The square boxes are the ${\bar{C}}_{o_i}$ matrices and s₀,s₁,s₂ and s₃ are scaling factors. The gray lines show the dependencies between the ${\bar{C}}_{o_i}$ matrices, while the solid black arrows show how the scaling factors are computed. For example, s₀ is computed directly from ${\bar{C}}_0$ as the sum of all its entries. s₂ is the sum of all entries in ${\bar{C}}_2$ times s₁ and s₀.
