get_physical
(obj)¶ NAME:
get_physicalPURPOSE:
return the velocity and length units for converting between physical and internal units as a dictionary for any galpy object, so they can easily be fed to galpy routinesINPUT:
obj - a galpy object or list of such objects (e.g., a Potential, list of Potentials, Orbit, actionAngle instance, DF instance)OUTPUT:
Dictionary {‘ro’:length unit in kpc,’vo’:velocity unit in km/s}; note that this routine will always return these conversion units, even if the obj you provide does not have units turned onHISTORY:
