Fields
------

- rCos - :doc:`/_capnp/data/Float64Tensor`

  Tensor of shape [..., nToroidalCoeffs, nPoloidalCoeffs]

- zSin - :doc:`/_capnp/data/Float64Tensor`

  Tensor of shape [..., nToroidalCoeffs, nPoloidalCoeffs]

- toroidalSymmetry - UInt32 = 1

  Multiplier for toroidal mode number (e.g. 5 for W7-X)

- nTurns - UInt32 = 1

  Divisor for toroidal mode number. Usually 1, but can equal a different number if the surface has an nTurns \* 2pi periodic structure, such as a magnetic island (in this case this would be the island's m number

- nTor - UInt32

  Maximum toroidal mode number.

- mPol - UInt32

  Maximum poloidal mode number

- anonymous union - union

  - symmetric - Void

    Indicator that the surfaces are Stellarator-symmetric

  - nonSymmetric - group

    - rSin - :doc:`/_capnp/data/Float64Tensor`

      Tensor of shape [..., nToroidalCoeffs, nPoloidalCoeffs]

    - zCos - :doc:`/_capnp/data/Float64Tensor`

      Tensor of shape [..., nToroidalCoeffs, nPoloidalCoeffs]
