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:
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.
