Orbit.
flip
(inplace=False)[source]¶ NAME:
flipPURPOSE:
‘flip’ an orbit’s initial conditions such that the velocities are minus the original velocities; useful for quick backward integration; returns a new Orbit instanceINPUT:
inplace= (False) if True, flip the orbit in-place, that is, without returning a new instance and also flip the velocities of the integrated orbit (if it exists)OUTPUT:
Orbit instance that has the velocities of the current orbit flipped (inplace=False) or just flips all velocities of current instance (inplace=True)HISTORY:
