actionAngleStaeckel¶
- class galpy.actionAngle.actionAngleStaeckel(*args, **kwargs)[source]¶
Action-angle formalism for axisymmetric potentials using Binney (2012)’s Staeckel approximation
- __init__(*args, **kwargs)[source]¶
- NAME:
__init__
- PURPOSE:
initialize an actionAngleStaeckel object
- INPUT:
pot= potential or list of potentials (3D)
delta= focus (can be Quantity)
useu0 - use u0 to calculate dV (NOT recommended)
c= if True, always use C for calculations
order= (10) number of points to use in the Gauss-Legendre numerical integration of the relevant action, frequency, and angle integrals
ro= distance from vantage point to GC (kpc; can be Quantity)
vo= circular velocity at ro (km/s; can be Quantity)
OUTPUT:
