pvTvz
(vT, vz, R, z, gl=True, ngl=20, nsigma=4.0)¶ NAME:
pvTvzPURPOSE:
calculate the marginalized (vT,vz) probability at this location (NOT normalized by the density)INPUT:
vT - tangential velocity (can be Quantity)
vz - vertical velocity (can be Quantity)
R - radius (can be Quantity)
z - height (can be Quantity)
gl - use Gauss-Legendre integration (True, currently the only option)
ngl - order of Gauss-Legendre integration
nsigma - sets integration limits to [-1,+1]*nsigma*sigma_R(R) for integration over vR (default: 4)
OUTPUT:
p(vT,vz,R,z)HISTORY:
2012-12-22 - Written - Bovy (IAS) 2018-01-12 - Added Gauss-Legendre integration prefactor nsigma/2 - Trick (MPA)
