arpes.analysis.pocket.pocket_parameters(data, kf_method=None, sel=None, method_kwargs=None, **kwargs)[source]#

Estimates pocket center, anisotropy, principal vectors, and extent.

Since data can be converted forward it is generally advised to do this analysis in angle space before conversion if the pocket is not very large.

Parameters:
  • data – The input kx-ky or 2D angle map.

  • kf_method – How to determine k_F for each slice.

  • sel – An energy selection window near the Fermi surface.

  • method_kwargs – Passed to the kf determination method

  • kwargs – Passed to the radial selection method.

Returns:

Extracted asymmetry parameters.
