- Potential.vcirc(R, phi=None, t=0.0)[source]¶
Calculate the circular velocity at R in this potential.
- Parameters:
R (float or Quantity) – Galactocentric radius.
phi (float, optional) – Azimuth to use for non-axisymmetric potentials.
t (float or Quantity, optional) – Time.
- Returns:
Circular rotation velocity.
- Return type:
float or Quantity
