integrate_dxdv is currently only supported for planarOrbit instances. getOrbit_dxdv is therefore also only supported for those types of Orbit.
NAME:
getOrbit_dxdv
PURPOSE:
return a previously calculated integration of a small phase-space volume (with integrate_dxdv)
INPUT:
(none)
OUTPUT:
array orbit[nt,nd*2] with for each t the dxdv vector
