grasp2alm.BeamCut.to_polar

BeamCut.to_polar(copol_axis='x')

Converts beam in “cut” format to Stokes parameters on a polar grid. Assumes that cuts are evenly spaced in theta. The value of copol specifies the alignment of the co-polar basis (‘x’ or ‘y’) of the input GRASP file.

Parameters:

copol_axis (str) – The axis of copolarization. Must be either ‘x’ or ‘y’.

Returns:

The beam in polar coordinates.

Return type:

BeamPolar

Raises:

ValueError – If the beam is not in the expected format.
