Figure 3
A flowchart illustrating the steps of the modulus constraint. The process begins with the current intensity function shown in the orange box and follows the solid black arrows between the dark blue boxes. Dashed arrows between the light blue boxes indicate additional steps required to account for lossy transformation processes. The green boxes illustrate the calculation of eigenvectors and eigenvalues from the harmonic order matrix and the correlation function, and where they are used in the transformation steps. After applying the modulus constraint, the intermediate intensity function shown in the yellow box is produced.
