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.

Third-party software notices

Jungfraujoch is licensed under GPL-3.0 (see LICENSE); the FPGA design is licensed under CERN-OHL-S-2.0 (see fpga/LICENSE). It builds on a number of third-party components, acknowledged below as required by their licenses.

This file is the human-readable manifest. The verbatim license texts live in the licenses/ directory (regenerate with bash licenses/COLLECT.sh). The frontend's bundled JavaScript dependencies are listed separately in frontend/dist/THIRD_PARTY_LICENSES.txt, generated at build time (npm run licenses).

All licenses below are GPL-3.0-compatible.

Fetched at build time and statically linked into the C++ binaries

These are downloaded by CMake (FetchContent / ExternalProject) during the first configure and linked into the Jungfraujoch executables.

Frontend (npm) dependencies

The React/TypeScript frontend (frontend/) bundles a large transitive tree of npm packages, overwhelmingly MIT/ISC/BSD/Apache-2.0 licensed. Their full notices are generated automatically:

cd frontend && npm run licenses     # writes dist/THIRD_PARTY_LICENSES.txt

The generated file is produced as part of the frontend build target and installed alongside the served frontend, so the shipped web UI carries its own attribution.

Notes on weak-copyleft and attribution-sensitive components

  • MPL-2.0 (Eigen, GEMMI, libzmq, traccc): file-level copyleft. GEMMI is vendored in gemmi_gph/ in trimmed form; libzmq is fetched at build time; Eigen is provided externally (header-only). The corresponding source is available from each project upstream.
  • GEMMI's own bundled third-party headers — PEGTL, sajson, fast_float, half, pocketfft and tinydir, all under gemmi_gph/gemmi/third_party/ — are listed separately above rather than being absorbed into GEMMI's row: they are other authors' code under other licences (MIT, BSD and Apache/MIT/BSL), and GEMMI's MPL-2.0 does not speak for them. Their terms are carried in the headers themselves rather than in LICENSE files, so the licenses/*.txt copies are kept by hand; only PEGTL ships a LICENSE, which COLLECT.sh copies.
  • traccc is the one entry that is not a vendored directory. Its sparse connected-component labelling enters two otherwise first-party files: StrongPixelSet.cpp adapts the SparseCCL source, and SpotExtractorGPU.cu follows the design of its GPU counterpart. MPL-2.0 is file-level, so both files name the origin at the top and are covered by licenses/traccc.txt. See ACKNOWLEDGEMENT.md for the citation.
  • FFTW is GPL-2.0-or-later — compatible with, and absorbed by, this project's GPL-3.0 license.
  • Apache-2.0 components: where upstream ships a NOTICE file, it is reproduced in the corresponding licenses/ text.
  • Qt (LGPL-3.0) and NVIDIA CUDA (EULA) carry redistribution conditions beyond a copyright notice; see their dedicated notice files. The verbatim LGPL-3.0 and CUDA EULA texts are bundled (licenses/Qt6-LGPL-3.0.txt, licenses/NVIDIA-CUDA-EULA.txt); the CUDA EULA is the one shipped with CUDA Toolkit 12.8 — replace it if you build against a different toolkit version.
