The Extrasolar Planets Encyclopaedia (exoplanet.eu):
  The planet catalogue in docs/results/exoplanet_catalogue.json,
  docs/results/exoplanet_map.json, docs/results/methods_examples.json and
  docs/results/population_stats.json, and in the built site's
  site/assets/data/ (catalogue.json, exoplanet_map.csv, galaxy.json),

NASA TESS data from MAST:
  TESS SPOC light curves and target pixel files, read from the Mikulski Archive
  for Space Telescopes (MAST) at the Space Telescope Science Institute. The stored
  run (runs/tess-pi-men-s1/: subject plots, classifications, candidates), the
  sweep records (docs/sweep/), the vetting results (docs/results/pi_men_*) and
  the report's plots (site/evidence/report/assets/) are derived from them, with each
  file's sha256 recorded. The neighbour tables in docs/results/pi_men_s2_vetting.*
  hold values from the TESS Input Catalog (TIC), read from MAST.

  TESS mission is provided by NASA's Science Mission Directorate. STScI is
  operated by the Association of Universities for Research in Astronomy, Inc.,
  under NASA contract NAS 5-26555.

NASA Exoplanet Archive (TOI table and planetary parameters):
  The TESS Objects of Interest table (table toi; the frozen 662-TOI benchmark
  sample in docs/results/benchmark_toi_sample.json and the leaderboard inputs
  derived from it, fetched 2026-10-19) and pi Men c's parameters (table ps:
  docs/results/pi_men_reference.json, docs/results/pi_men_crossmatch.json), from

Claret 2017 limb darkening:
  Quadratic limb-darkening coefficients for the TESS band, Claret, A. 2017,
  A&A 600, A30 (doi:10.1051/0004-6361/201629705), table J/A+A/600/A30/tableab
  read through VizieR (CDS, Strasbourg, France) on 2026-10-19:
  docs/results/claret2017_tess_quadratic.json (scripts/fetch_claret2017.py).
  This research has made use of the VizieR catalogue access tool, CDS,
  Strasbourg Astronomical Observatory, France.

WASP-39 b JWST spectrum (CC BY 4.0):
  The NIRSpec PRISM transmission spectrum and best-fit model of WASP-39 b from
  "Products and Models for 'A benchmark JWST near-infrared spectrum for the
  exoplanet WASP-39 b'", Zenodo, doi:10.5281/zenodo.10161743, licensed under
  CC BY 4.0; Carter et al. 2024, Nature Astronomy 8, 1008
  (doi:10.1038/s41550-024-02292-x). Binned and converted to transit depth in
  docs/results/wasp39b_jwst_spectrum.json (scripts/fetch_wasp39b_spectrum.py)
  and drawn in the app's Methods chapter, which cites it.

SIMBAD:
  The ICRS coordinates of pi Mensae (HD 39091) in docs/results/targets.json, used
  only to place the star on the sky map. This research has made use of the
  SIMBAD database, operated at CDS, Strasbourg, France.

Published values:
  Reference values for comparison (for example Huang et al. 2018, ApJL 868, L39,
  for pi Men c, and the survey footprints in docs/results/survey_coverage.json,
  computed with tess-point and K2fov) are cited where they are used.
