AxisAlignedBeamTilt

class abtem.tilt.AxisAlignedBeamTilt(tilt=0.0, direction='x')

Bases: DistributionFromValues

Class describing tilt(s) aligned with an axis.

Parameters:

• tilt (array of BeamTilt) – Tilt along the given direction with an optional spread of values.

• direction (str) – Cartesian axis, should be either ‘x’ or ‘y’.

__init__(tilt=0.0, direction='x')

Methods
