"""
macro_RSXS_smooth_sweep
This method wraps up the bluesky/ophyd codeand allows users to drive
the LU20 experiment with minimal code overhead. It contains the following
bluesky plan.
This bluesky plan moves a 2-axis actuator across multiple traversals of a
sample. The plan traverses the entirety of the stroke_height (y-axis) and
after each traversal, steps in the x-axis by the stroke_spacing.It may be
configured to scan in only a single direction and shutter the beam for the
opposite direction. This removes the shutter at the beginning of the plan
and reinserts it at the end. At the end of the plan, the sample is moved to
its original y-axis position but with an x-axis posiiton ready for the next
run. For more details about the path, see the documentation of the
xy_sequencer, the method that generates the sample's path.
Parameters
----------
stroke_height : float
Vertical distance (y-axs) of each stroke.
stroke_spacing : float
Horizontal distance between individual strokes.
n_strokes : int
Number of strokes to complete.
both_directions : bool, optional
Defaults to True. If this value is true the beam will be scanned across
the sample while moving in both vertical directions. If false, the beam
is only scanned in a single direction.
