Absolute fermat spiral scan, centered around (x_start, y_start)
- Parameters:
- detectorslist
list of ‘readable’ objects
- x_motorobject
any ‘settable’ object (motor, temp controller, etc.)
- y_motorobject
any ‘settable’ object (motor, temp controller, etc.)
- x_startfloat
x center
- y_startfloat
y center
- x_rangefloat
x width of spiral
- y_rangefloat
y width of spiral
- drfloat
delta radius
- factorfloat
radius gets divided by this
- dr_yfloat, optional
Delta radius along the major axis of the ellipse, if not specifed defaults to dr.
- tiltfloat, optional
Tilt angle in radians, default 0.0
- per_stepcallable, optional
hook for customizing action of inner loop (messages per step). See docstring of
bluesky.plan_stubs.one_nd_step()(the default) for details.- mddict, optional
