# Notices for third-party test data

`spc-parser` itself is MIT licensed (see `LICENSE`) and the published npm package
contains only its own sources: the files below are test fixtures, excluded from
the package by `src/.npmignore`. They are kept in the repository so that the
behaviour of real instruments stays covered by the test suite.

Every fixture is a spectrum or a header recorded by an instrument. Each one is
listed with its URL, licence, attribution and SHA-256 in the `PROVENANCE.md` of
its folder, and `src/__tests__/fixtures.test.ts` verifies those hashes:

- `src/galactic/__tests__/data/corpus/PROVENANCE.md`
- `src/uvProbe/__tests__/data/corpus/PROVENANCE.md`
- `src/__tests__/data/PROVENANCE.md`
