cartesian_to_poincare_polar¶

gala.coordinates.cartesian_to_poincare_polar(w)[source]¶

Convert an array of 6D Cartesian positions to Poincaré symplectic polar coordinates. These are similar to cylindrical coordinates.

Parameters:

w : array_like

Input array of 6D Cartesian phase-space positions. Should have shape (norbits,6).

Returns:

new_w : ndarray

Points represented in 6D Poincaré polar coordinates.
