Query: Optimized quasisymmetric stellarators are consistent with the
  Garren-Boozer construction   Most quasisymmetric stellarators to date have been designed by numerically
optimizing the plasma boundary shape to minimize symmetry-breaking Fourier
modes of the magnetic field strength $B$. At high aspect ratio, a faster
approach is to directly construct the plasma shape from the equations of
quasisymmetry near the magnetic axis derived by Garren and Boozer [Phys Fluids
B 3, 2805 (1991)]. Here we show that the core shape and rotational transform of
many optimization-based configurations can be accurately described by this
direct-construction approach. This consistency supports use of the near-axis
construction as an accurate analytical model for modern stellarator
configurations.
