Thanks! Couple of comments, I think there are some additional things we need to set too:

• num_frames_chunks
• The file name/directory e.g. everything in set_odin_pvs
• dev_shm

[DominicOram]

Should: Why do you need an inner plan here?

[shihab-dls]

I think it was the first thing I wrote for structure and left in for no reason; removing as definitely not needed :0

[DominicOram]

Should: We probably want to group these things as it makes it more async (even if Tom/Gary assure us it's instantaneous). Then we will need to wait on them at some point so we should add that optionally too e.g.

Suggested change

	def set_mx_settings_pvs(eiger: EigerDetector, detector_params: DetectorParams):
	beam_x_pixels, beam_y_pixels = detector_params.get_beam_position_pixels(
	detector_params.detector_distance
	)
	yield from bps.abs_set(eiger.drv.beam_centre_x, beam_x_pixels)
	yield from bps.abs_set(eiger.drv.beam_centre_y, beam_y_pixels)
	yield from bps.abs_set(eiger.drv.det_distance, detector_params.detector_distance)
	yield from bps.abs_set(eiger.drv.omega_start, detector_params.omega_start)
	yield from bps.abs_set(eiger.drv.omega_increment, detector_params.omega_increment)
	def set_mx_settings_pvs(eiger: EigerDetector, detector_params: DetectorParams, group="mx_settings", wait=True):
	beam_x_pixels, beam_y_pixels = detector_params.get_beam_position_pixels(
	detector_params.detector_distance
	)
	yield from bps.abs_set(eiger.drv.beam_centre_x, beam_x_pixels, group)
	yield from bps.abs_set(eiger.drv.beam_centre_y, beam_y_pixels, group)
	yield from bps.abs_set(eiger.drv.det_distance, detector_params.detector_distance, group)
	yield from bps.abs_set(eiger.drv.omega_start, detector_params.omega_start, group)
	yield from bps.abs_set(eiger.drv.omega_increment, detector_params.omega_increment, group)
	if wait:
	yield from bps.wait(group)

This is a pattern we've used in a few places e.g. https://github.com/DiamondLightSource/mx-bluesky/blob/11c8a31f05dfc8421b9ebf205cc49598cd8806be/src/mx_bluesky/beamlines/i24/serial/setup_beamline/setup_beamline.py#L58. It allows the caller to have some flexibility in timings.

We should do the same for other plans in this file too
