galpy.df.quasiisothermaldf.meanjr

quasiisothermaldf.meanjr(R, z, nsigma=None, mc=True, nmc=10000, **kwargs)[source]

Calculate the mean radial action by marginalizing over velocity

Parameters:

  • R (float or Quantity) – Radius at which to calculate this

  • z (float or Quantity) – Height at which to calculate this

  • nsigma (float, optional) – Number of sigma to integrate the velocities over

  • mc (bool, optional) – If True, calculate using Monte Carlo integration

  • nmc (int, optional) – If mc, use nmc samples

  • **kwargs (dict) – scipy.integrate.tplquad kwargs epsabs and epsrel

Returns:

Mean jr

Return type:

float
