quasiisothermaldf.tilt(R, z, nsigma=None, mc=False, nmc=10000, gl=True, ngl=10, **kwargs)

NAME:

tilt

PURPOSE:

calculate the tilt of the velocity ellipsoid by marginalizing over velocity

INPUT:

R - radius at which to calculate this

z - height at which to calculate this

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

OUTPUT:

tilt in degree
