artof 1.4.0

The ARTOF is a tool to read, process and analyze data collected from angle resolved time of flight (ARToF) electron analyzer.

artof

The artof package is a jupyter notebook tool to read, process and analyze data collected from angle resolved time of flight (ARTOF) sensors.

Getting started

To use this package python version >=3.10 is needed. The installation can be done using the command:

pip install artof

Documentation

The documentation can be found here. It is automatically generated from the docstrings in all python classes.

Workflow

The implementation of a new feature should be conducted as follows:

1. Create a new branch with a sensible name as a fork from dev.
2. Implement features including documentation.
3. If required, make changes to the Sphinx documentation under docs/source/.
4. Check if all existing tests are still working (cmd: pytest) and write new test functions.
5. If there were changes to dev since the initial fork, merge it into your branch and resolve conflicts. Check again if all tests are running.
6. Make sure the pylint rating of each file is 8 or higher. To do so run

pylint src/artof/{file}

7. Update documentation in the ./docs folder using .rst and sphinx. For automatic doc generation use .. automodule:: artof.{module} or .. autoclass:: artof.{module}.{class}. Do not forget to add new .rst-files to index.
8. Test the doc generation and ensure there are no warnings (else the pipeline will fail). To do so run

sphinx-build -M html docs/source docs/build

9. Increase version number in setup.cfg and CITATION.cff file.
10. Push all changes to the remote repository and create a merge request to dev.
11. Make sure all tests succeed in the pipeline and merge.
12. When enough changes accumulate, create a merge request to main once enough features accumulated to roll out a new version. Make again sure all test pipelines succeed.
13. After merging to main a new version of the package is released to PyPi upon a successful pipeline run.

Major releases

In case of major releases, it is recommended to deploy seperate version for the docs, that will be available in the future. To do so, add a new entry to the versions.json-file (root directory).

[
    {
        "name": "latest (main)",
        "version": "main",
        "url": "https://artof-42d889.pages.hzdr.de/main/"
    },
    {
        "name": "testing (dev)",
        "version": "dev",
        "url": "https://artof-42d889.pages.hzdr.de/dev/"
    },  
    ...  
    {
        "name": "vx.x.x",
        "version": "vx.x.x",
        "url": "https://artof-42d889.pages.hzdr.de/vx.x.x/"
    },
]

After getting this version merged onto the main branch, add a tag to the according commit with the exact name of the version (vx.x.x). A new page deployment will be run automatically.

Terminology

General

• Iteration: One full measurements cycle
• Step/Frame: Step within one iteration
• Window: Span of iterations used for spectral evolution.
• Trigger period: Time between two triggers. Usually the trigger is synched to revolution period (BESSY, approx. 800 ns / 32000 ticks).

Pump probe

• Run: Individual run, where settings like f.e. the delay stage or oscillator delay have been changed.
• Revolution: Revolutions of the synchrotron, which range from -1 to 205. Revolution 0 is the revolution of the pumb pulse.
• Revolution period: Average time between two revolutions, often given in TDC ticks ( approx. 800 ns / 32000 ticks).
