quasiisothermaldf.pvR(vR, R, z, gl=True, ngl=20, nsigma=4.0, vTmax=1.5)[source]

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

Parameters:

  • vR (float or Quantity) – Radial 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.

  • nsigma (float, optional) – Number of sigma to integrate the velocities over.

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

Returns:

p(vR,R,z).

Return type:

float
