Query: Representing the boundary of stellarator plasmas   In stellarator optimization studies, the boundary of the plasma is usually
described by Fourier series that are not unique: several sets of Fourier
coefficients describe approximately the same boundary shape. A simple method
for eliminating this arbitrariness is proposed and shown to work well in
practice.
