galpy.util.conversion.get_physical

galpy.util.conversion.get_physical(obj, include_set=False)[source]

NAME:

get_physical

PURPOSE:

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 routines

INPUT:

obj - a galpy object or list of such objects (e.g., a Potential, list of Potentials, Orbit, actionAngle instance, DF instance)

include_set= (False) if True, also include roSet and voSet, flags of whether the unit is explicitly set in the object

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 on
