USAGE

.OPERATION: FT R

.FIRST INPUT FILE: FOU001
[Enter file name of first Fourier transform.]

.SECOND INPUT FILE: FOU002
[Enter file name of second Fourier transform.]

.OUTPUT FILE: FOU003
[Enter output file name that will contain the new Fourier transform.]

NOTES

This operation can be used to implement the "amplitude replace" step in a Gerchberg-Saxton or solvent flattening scheme.
