rE
(*args, **kwargs)[source]¶ NAME:
rEPURPOSE:
calculate the radius of a circular orbit with the same energyINPUT:
pot= potential instance or list of such instances
ro= (Object-wide default) physical scale for distances to use to convert (can be Quantity)
vo= (Object-wide default) physical scale for velocities to use to convert (can be Quantity)
use_physical= use to override Object-wide default for using a physical scale for output
OUTPUT:
