meanvR
(R, z, nsigma=None, mc=False, nmc=10000, gl=True, ngl=10, **kwargs)[source]¶ NAME:
meanvRPURPOSE:
calculate the mean radial velocity by marginalizing over velocityINPUT:
R - radius at which to calculate this (can be Quantity)
z - height at which to calculate this (can be Quantity)
OPTIONAL INPUT:
nsigma - number of sigma to integrate the velocities over
scipy.integrate.tplquad kwargs epsabs and epsrel
mc= if True, calculate using Monte Carlo integration
nmc= if mc, use nmc samples
gl= if True, calculate using Gauss-Legendre integration
ngl= if gl, use ngl-th order Gauss-Legendre integration for each dimension
