blissoda.id31.optimize_exposure.optimal_exposure_conditions(mot, start, stop, intervals, detector, tframe=0.2, nframes_measure=1, nframes_default=3, desired_counts=100000.0, reduce_desired_deviation=True, expose_with_integral_frames=False, maxint_sigma=2, mask=None)[source]#

Return the optimal attenuator and exposure time for each motor position. Measurements are done at the current attenuator position.

Parameters:

  • mot

  • start

  • stop

  • intervals

  • detector – lima detector object

  • tframe (float) – time of a single frame in accumulation mode

  • desired_counts (float) – we want to be close to this maximum pixel value

  • nframes_measure (int) – number of frames used for optimization measurements

  • nframes_default (int) – try modify attenuators for this number of frames

  • reduce_desired_deviation (bool) – reduce deviation from the desired counts

  • expose_with_integral_frames (bool) – exposure time is n x frame time with n integral or not

  • maxint_sigma (float) – gaussian smoothing sigma in pixels before getting the maximum frame intensity

  • mask (Optional[numpy.ndarray]) – Mask to apply to images during exposure time optimization

Return type:

List[ExposureCondition | None]

Returns:

list of optimal exposure conditions
