# 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)
