Potential.
dens
(R, z, phi=0.0, t=0.0, forcepoisson=False)¶ NAME:
densPURPOSE:
evaluate the density rho(R,z,t)INPUT:
R - Cylindrical Galactocentric radius (can be Quantity)
z - vertical height (can be Quantity)
phi - azimuth (optional; can be Quantity)
t - time (optional; can be Quantity)
KEYWORDS:
forcepoisson= if True, calculate the density through the Poisson equation, even if an explicit expression for the density existsOUTPUT:
