galpy.df.diskdf.skewvR

diskdf.skewvR(R, romberg=False, nsigma=None, phi=0.0)[source]

Calculate skew in vR at R by marginalizing over velocity.

Parameters:

  • R (float or Quantity) – Radius at which to calculate <vR>.

  • romberg (bool, optional) – If True, use a romberg integrator (default: False).

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

  • phi (float, optional) – Azimuth (in radians) at which to calculate the skew in vR.

Returns:

Skew in vR.

Return type:

float
