Notes:
A practical method of obtaining the best helical parameters p/P and p, where p is the rise per unit length along the screw axis and P is the pitch of the helix, is given, which consists of a graphical method followed by a least-squares analysis, and is particularly useful when the helix is non-integral and when the diffraction pattern is complicated by the existence of other crystalline or amorphous phases. The extension of the method to a coiled coil is also described.
