- galpy.potential.evaluateplanarPotentials(Pot, R, phi=None, t=0.0, dR=0, dphi=0)[source]¶
NAME:
evaluateplanarPotentials
PURPOSE:
evaluate a (list of) planarPotential instance(s)
INPUT:
Pot - (list of) planarPotential instance(s)
R - Cylindrical radius (can be Quantity)
phi= azimuth (optional; can be Quantity)
t= time (optional; can be Quantity)
dR=, dphi= if set to non-zero integers, return the dR,dphi’t derivative instead
OUTPUT:
Phi(R(,phi,t))
