galpy.potential.Potential.__call__

Potential.__call__(R, z, phi=0.0, t=0.0, dR=0, dphi=0)

NAME:

__call__

PURPOSE:

evaluate the potential at (R,z,phi,t)

INPUT:

R - Cylindrical Galactocentric radius

z - vertical height

phi - azimuth (optional)

t - time (optional)

dR= dphi=, if set to non-zero integers, return the dR, dphi’t derivative instead

OUTPUT:

Phi(R,z,t)
