Detailed Description

Calculate \(R\), \(Z\) & \(\lambda\) and derivatives in VMEC coordinates.

This is done at the grid points given by the variables theta_E and zeta_E (contained in trigon_factors) and at every normal point.

The derivatives are indicated by the variable deriv which has 3 indices

Note

There is no HELENA equivalent because for HELENA simulations, \(R\) and \(Z\) are not necessary for calculation of the metric coefficients, and \(\lambda\) does not exist.
