v1.0.0-rc.166 (#76)
* `rugnux --mode calibration` writes `<prefix>.json` beside the `.poni`, whose `dataset_settings` member is a `jfjoch_broker` `dataset_settings` body as it stands.
* `rugnux` and `jfjoch_viewer` read PILATUS miniCBF sweeps natively, without conversion.
* Masters written by other facilities open, including Eiger 1.x and third-party NXmx variants.
* `rugnux` measures the beam centre on every run, and indexes with it when the file's value indexes nothing.
* A detector swung out on a 2theta arm is placed where the file says it stands, and the calibration can hold the tilt fixed.
* `rugnux` writes the unmerged MTZ by default, and a P1 merge beside it, so a wrong space group can be re-merged without reprocessing.
* Significant improvements to symmetry handling in `rugnux`: the lattice, the point group, the setting and the systematic absences.
* The `rugnux` report gives the resolution the CC1/2 fit reached, beside the range the reflections were written to.
* The `rugnux` report gives the twinning statistics measured before the space group was decided, beside the ones measured after.
* The `rugnux` report gives the strong-direction diffraction limit, and warns when CC1/2 is not monotone with resolution.
* `rugnux` ranks screw axes on the evidence their absences carry, rather than on how many control reflections a candidate happens to have.
* Twinning is no longer reported when the L-test contradicts it.
* The `rugnux` report gives the detector tilt, the measured tilt and the direct beam beside the beam centre, and a post-refined beam centre is judged against the run's own measurement rather than the file's.
* `--no-refine-tilt` holds the detector tilt at the value in the file, instead of zeroing it, when the calibration starts from the spots.
* The `jfjoch_viewer` grid scan view draws the cells in the proportion of the scan steps, so the map has the shape of the scanned area.

# IndexingSettings
Settings for crystallography indexing
## Properties
Name | Type | Description | Notes
------------ | ------------- | ------------- | -------------
**algorithm** | [**IndexingAlgorithm**](IndexingAlgorithm.md) | | [default to IndexingAlgorithm.FFBIDX]
**fft_max_unit_cell_a** | **float** | Largest unit cell to be indexed by FFT algorithm; parameter value affects execution time of FFT | [default to 250]
**fft_min_unit_cell_a** | **float** | Smallest unit cell to be indexed by FFT algorithm; parameter value affects execution time of FFT | [default to 10.0]
**fft_high_resolution_a** | **float** | Sets how finely the FFT samples each search direction: it fixes the extent of the projection histogram, and with it the transform size, so it affects execution time and memory of FFT. It does NOT filter spots - every spot is projected whatever its resolution, so raising it does not make the transform see a coarser subset of the data. There is also correlation between smallest unit cell and this value, which need to be checked for very small systems. | [default to 2.0]
**fft_num_vectors** | **int** | Number of search directions for the FFT algorithm; parameter value affects execution time of FFT. | [default to 16384]
**tolerance** | **float** | Acceptance tolerance for spots after the indexing run - the larger the number, the more spots will be accepted |
**thread_count** | **int** | Thread count for indexing algorithm |
**geom_refinement_algorithm** | [**GeomRefinementAlgorithm**](GeomRefinementAlgorithm.md) | |
**unit_cell_dist_tolerance** | **float** | Relative distance tolerance for unit cell vs. reference; Lattices outside given tolerance will be ignored | [default to 0.05]
**viable_cell_min_spots** | **int** | Minimum number of indexed spots required for a cell to be considered viable | [default to 10]
**index_ice_rings** | **bool** | Include spots marked as ice rings in the indexing run. If &#x60;dataset_settings&#x60; doesn&#39;t have &#x60;detect_ice_rings&#x60; on, this option will have no effect on processing. | [default to False]
**rotation_indexing** | **bool** | | [default to False]
**rotation_indexing_min_angular_range_deg** | **float** | | [default to 20.0]
**rotation_indexing_angular_stride_deg** | **float** | | [default to 0.5]
**blocking** | **bool** | Indexing in Jungfraujoch goes with a dedicated thread pool. If set to false, the thread pool is non-blocking, i.e. if there are no threads available, image indexing will be skipped. This option is recommended for real-time processing at high frame rates. If set to true, the thread pool will block until a thread is available. | [default to True]
## Example
```python
from jfjoch_client.models.indexing_settings import IndexingSettings
# TODO update the JSON string below
json = "{}"
# create an instance of IndexingSettings from a JSON string
indexing_settings_instance = IndexingSettings.from_json(json)
# print the JSON string representation of the object
print(IndexingSettings.to_json())
# convert the object into a dict
indexing_settings_dict = indexing_settings_instance.to_dict()
# create an instance of IndexingSettings from a dict
indexing_settings_from_dict = IndexingSettings.from_dict(indexing_settings_dict)
