adjacent_toroidal_angles

cherab.lhd.machine.wall.adjacent_toroidal_angles(phi: float, phis: ndarray) → tuple[int64, int64]Source

Generate adjacent toroidal angles.

If phis = [0.0, 0.5, 1.0,..., 18.0] and given phi = 0.75, then (left, right) adjacent toroidal angles are (0.5, 1.0), each index of which is (1, 2), respectively.

Parameters:

phifloat

Toroidal angle between 0 and 18 degree.

phis(N, ) array_like

1D array of toroidal angles.

Returns:

tuple[int, int]

(left, right) adjacent toroidal angle indices.
