How to cite

If Magνs contributed to work you are publishing, please cite it. A citation is what makes the effort of maintaining a package visible, and it lets a reader reproduce what you did.

Cite the software

Until the accompanying paper is available, cite the software itself, including the version you used — results can depend on it, and Magνs records its own:

import magnus
print(magnus.__version__)

@software{Magnus,
  author  = {Bustamante, Mauricio},
  title   = {{Mag$\nu$s: neutrino oscillation probabilities via the
              Magnus expansion}},
  url     = {https://github.com/mbustama/Magnus},
  version = {1.0.0rc1},
  year    = {2026}
}

Replace version with the one you actually ran.

What to say in the text

Enough for a reader to know what was computed and how precisely. In practice that is three things:

  1. The version, as above.

  2. The tolerance you asked for (rtol/atol, or the fixed n_slabs and n_tpts_per_slab if you disabled the refinement). Note that these are a stopping criterion rather than a bound on the error — see What rtol and atol actually control — so quoting them describes the request, not the achieved accuracy.

  3. The strategy, if you did not use the default. strategy='auto' and strategy='magnus' can differ by far more than the tolerance on solar configurations, so it is worth stating which one produced the numbers.

If accuracy is central to your result, convergence_info reports what the refinement ladder actually did, including whether it converged or hit a cap.

Citing the method

The Magnus expansion itself, and the commutator-free Gauss–Legendre integrators Magνs uses by default, are due to others. The References page has the full bibliography; the two worth citing alongside the software are the review by Blanes, Casas, Oteo and Ros, and the high-order integrators of Blanes, Casas and Ros.
