Initialize an actionAngleAdiabaticGrid object

Parameters:

  • pot (Potential or list of Potential instances) – The potential (instance) or list of potentials (instances) that make up the potential

  • zmax (float) – Maximum height to which to calculate Ez

  • gamma (float) – Replace Lz by Lz+gamma Jz in effective potential

  • Rmax (float) – Maximum radius to which to calculate Er

  • nR (int) – Number of radii to use in the grid

  • nEz (int) – Number of Ez values to use in the grid

  • nEr (int) – Number of Er values to use in the grid

  • nLz (int) – Number of Lz values to use in the grid

  • numcores (int) – Number of cores to use for multi-processing

  • ro (float or Quantity, optional) – Distance scale for translation into internal units (default from configuration file).

  • vo (float or Quantity, optional) – Velocity scale for translation into internal units (default from configuration file).
