galpy.potential.Potential.dens

Potential.dens(R, z, phi=0.0, t=0.0, forcepoisson=False)[source]

Evaluate the density rho(R,z,t).

Parameters:

  • R (float or Quantity) – Cylindrical Galactocentric radius.

  • z (float or Quantity) – Vertical height.

  • phi (float or Quantity, optional) – Azimuth (default: 0.0).

  • t (float or Quantity, optional) – Time (default: 0.0).

  • forcepoisson (bool, optional) – If True, calculate the density through the Poisson equation, even if an explicit expression for the density exists (default: False).

Returns:

rho (R,z,phi,t).

Return type:

float or Quantity
