cartesian_to_poincare_polar

gala.coordinates.cartesian_to_poincare_polar(w)

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

Parameters:

warray_like

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

Returns:

new_wndarray

Points represented in 6D Poincaré polar coordinates.
