evaluatePotentials
(Pot, R, z, phi=None, t=0.0, dR=0, dphi=0)¶ NAME:
evaluatePotentialsPURPOSE:
convenience function to evaluate a possible sum of potentialsINPUT:
Pot - potential or list of potentials
R - cylindrical Galactocentric distance (can be Quantity)
z - distance above the plane (can be Quantity)
phi - azimuth (can be Quantity)
t - time (can be Quantity)
dR= dphi=, if set to non-zero integers, return the dR, dphi’t derivative instead
OUTPUT:
Phi(R,z)HISTORY:
