galpy.potential.toVerticalPotential¶
- galpy.potential.toVerticalPotential(Pot, R, phi=None, t0=0.0)[source]¶
NAME:
toVerticalPotential
PURPOSE:
convert a Potential to a vertical potential at a given R: Phi(z,phi,t) = Phi(R,z,phi,t)-Phi(R,0.,phi0,t0) where phi0 and t0 are the phi and t inputs
INPUT:
Pot - Potential instance or list of such instances
R - Galactocentric radius at which to evaluate the vertical potential (can be Quantity)
phi= (None) Galactocentric azimuth at which to evaluate the vertical potential (can be Quantity); required if Pot is non-axisymmetric
t0= (0.) time at which to evaluate the vertical potential (can be Quantity)
OUTPUT:
(list of) linearPotential instance(s)
