`stxm_fast`	Initiates a 2-axis scan, targeting a maximum scan speed of around 10Hz.
`stxm_step`	Standard Bluesky grid scan adapted to use step size.

sm_bluesky.beamlines.p99.plans.stxm_fast(dets: list[Readable], count_time: float, step_motor: Motor, step_start: float, step_end: float, scan_motor: Motor, scan_start: float, scan_end: float, plan_time: float, point_correction: float = 1, step_size: float | None = None, home: bool = False, snake_axes: bool = True, md: dict[str, Any] | None = None) → Generator[Msg, Any, P]#

Initiates a 2-axis scan, targeting a maximum scan speed of around 10Hz. Calculates the number of data points based on the detector’s count time. If no step size is provided, aims for a uniform distribution of points. Adjusts scan speed and step size to fit the desired scan duration.

Parameters:

dets (list[Readable]) – List of detectors to use for the scan.
count_time (float) – Detector count time.
step_motor (Motor) – Motor for the slow axis.
step_start (float) – Starting position for the step motor.
step_end (float) – Ending position for the step motor.
scan_motor (Motor) – Motor for the continuously moving axis.
scan_start (float) – Starting position for the scan motor.
scan_end (float) – Ending position for the scan motor.
plan_time (float) – Desired duration of the scan in seconds.
point_correction (float, optional) – Scaling factor for the number of points, by default 1.
step_size (float, optional) – Step size for the slow axis, by default None.
home (bool, optional) – If True, move back to the original position after the scan, by default False.
snake_axes (bool, optional) – If True, perform a snake scan, by default True.
md (dict, optional) – Metadata for the scan, by default None.

Returns:

A Bluesky generator for the scan.

Return type:

MsgGenerator

Standard Bluesky grid scan adapted to use step size. Optionally moves back to the original position after scan.
