galpy.df.quasiisothermaldf.pvRvz

quasiisothermaldf.pvRvz(vR, vz, R, z, gl=True, ngl=20, vTmax=1.5)

Calculate the marginalized (vR,vz) probability at this location (NOT normalized by the density).

Parameters:

• vR (float or Quantity) – Radial velocity.

• vz (float or Quantity) – Vertical velocity.

• R (float or Quantity) – Radius.

• z (float or Quantity) – Height.

• gl (bool, optional) – If True, use Gauss-Legendre integration.

• ngl (int, optional) – If gl, use ngl-th order Gauss-Legendre integration for each dimension.

• vTmax (float, optional) – Sets integration limits to [0,vTmax] for integration over vT.

Returns:

p(vR,vz,R,z).

Return type:

float or Quantity
