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

NAME:

pvR

PURPOSE:

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

INPUT:

vR - radial 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_z(R) for integration over vz (default: 4)

vTmax - sets integration limits to [0,vTmax] for integration over vT (default: 1.5)

OUTPUT:

p(vR,R,z)
