Context

Decision 0009 verified the example pipelines on an anonymous sample data set (data/gamma, 2500 x 1834 x 17, 2021-2022), whose numbers filled the workflow guides. The manual (decision 0037) shows one data set to users: the maintainer chose Campi Flegrei (Sentinel-1 descending track 22, 92 dates 2019-2021, 981 x 4160 pixels, data/CampiFlegrei/gamma, described in data/CampiFlegrei/README.md): a known uplift with many PS and DS, which the tutorials already use. Two data sets with different numbers would confuse users and agents.

Decision

  • The sample data set of the examples and guides is Campi Flegrei: the [vars] defaults of examples/*.toml (reference 20200707, geocoding prefix 20200707, shape 981 x 4160, pixel spacings 2.329562 m and 13.9516 m) and the expected results, run times and figures of docs/workflows/ come from a run of the examples on it (first run: 2026-10-08).
  • The manual uses no other data set: its figures, the recorded agent session and the tutorial pages are Campi Flegrei.
  • data/gamma and data/rslc.zarr stay the data of the tests (tests/conftest.py); they document nothing.

Consequences

  • The rule of decision 0009 stands with the new data set: an example changes only after a run on Campi Flegrei, and the guide numbers are updated from that run.
  • The Xinpu tutorials stay in nbs/Tutorials/CLI/Xinpu/ for the maintainer but are not part of the manual.

Do not

  • Do not put numbers or figures of another data set into the guides or the manual.
  • Do not change the [vars] defaults of the examples to another data set.
