galpy.df.quasiisothermaldf.meanlz

quasiisothermaldf.meanlz(R, z, nsigma=None, mc=True, nmc=10000, **kwargs)

NAME:

meanlz

PURPOSE:

calculate the mean angular momemtum 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

OUTPUT:

meanlz
