Parameters:
  • R (float or Quantity) – Cylindrical Galactocentric radius.

  • z (float or Quantity) – Vertical height.

  • phi (float or Quantity, optional) – Azimuth. Default is None.

  • t (float or Quantity, optional) – Time. Default is 0.0.

  • v (float or Quantity, optional) – Current velocity in cylindrical coordinates. Required when including dissipative forces. Default is None.

Returns:

F_r – The spherical radial force F_r (R,z).

Return type:

float or Quantity
