bluesky.plans.rel_grid_scan¶

bluesky.plans.rel_grid_scan(detectors, *args, snake_axes=None, per_step=None, md=None)[source]¶

Scan over a mesh relative to current position.

Parameters

detectors: list

list of ‘readable’ objects

``*args``

patterned like (motor1, start1, stop1, num1,: motor2, start2, stop2, num2, motor3, start3, stop3, num3, … motorN, startN, stopN, numN)

The first motor is the “slowest”, the outer loop. For all motors except the first motor, there is a “snake” argument: a boolean indicating whether to following snake-like, winding trajectory or a simple left-to-right trajectory.

snake_axes: boolean or iterable, optional

which axes should be snaked, either False (do not snake any axes), True (snake all axes) or a list of axes to snake. “Snaking” an axis is defined as following snake-like, winding trajectory instead of a simple left-to-right trajectory. The elements of the list are motors that are listed in args. The list must not contain the slowest (first) motor, since it can’t be snaked.

per_step: callable, optional

hook for customizing action of inner loop (messages per step). See docstring of bluesky.plan_stubs.one_nd_step() (the default) for details.

md: dict, optional
