What they do

S1 Triage

ph_vetstar_vet, ph_vetstar_parse_report, ph_vetstar_status, ph_quicklook_physics

Run Vetstar on MAST data, or parse a Vetstar PDF with pymupdf. Red-flag checks catch BLS artefact periods, blind or zero-depth odd/even tests, placeholder depths, SPOC DV misfits, LS harmonics, R₂ > 2 R_Jup and centroid offsets. Also gives R₂ and a Planck-based T₂.

S2 Identity and contamination

ph_resolve_target, ph_contamination, ph_simbad_region

TIC v8.2 record. For each Gaia DR3 neighbour, the dip it would need, δ_nb = δ(1+f)/f, combined with the centroid σ.

S3 Novelty and literature

ph_vizier_sweep, ph_vizier_query, ph_simbad_references, ph_exofop, ph_exoplanet_archive_cone, ph_exoplanet_archive_query, ph_ads_search

Sweeps every VizieR catalogue and flags variability and period tables (this is how IJspeert+2024 turned up when SIMBAD missed it). Also ExoFOP TOIs and CTOIs, known planets and TOIs, and ADS through its API.

S4 Data

ph_mast_list_lightcurves, ph_mast_download_lightcurves

One light curve per sector, preferring SPOC 2-min, then TESS-SPOC FFI, then QLP. Cached locally, with warnings for artefact runs.

S5–S7 Analysis

ph_find_eclipses, ph_fit_ephemeris, ph_primary_stack, ph_secondary_search

Trapezoid mid-times flagged for full coverage. Weighted ephemeris with O−C. P/2, P/3 and 2P alias tests. Stacked primary (trapezoid, or with model="batman" a quadratic limb-darkened Mandel–Agol transit with Claret 2017 TESS limb-darkening priors: Rp/R★, b, a/R★, depth, T₁₄, T₂₃ with errors) and orbit geometry (k_min, a/R₁, b, e·sinω). Per-visit local-baseline secondary search with red-noise inflation and a lone-spike test.

S8 Figure

ph_make_figure

The single RNAAS figure: (a) stacked primary with model, (b) secondary search with a ±3σ band.

S9–S11 Manuscript

ph_rnaas_scaffold, ph_rnaas_check, ph_latex_build, ph_rnaas_submission_folder

AASTeX 7.0.1 skeleton with the AI disclosure, Vetstar credit and a \dataset entry for each MAST product. Checks RNAAS limits, compiles and renders pages, and builds a flat single-column submission folder that is tested standalone.

S10 References

ph_verify_references, ph_uat_search

Checks every DOI in a .bib/.tex against Crossref or DataCite (title, volume, page) and verifies UAT keyword IDs.

S12 Zenodo

ph_zenodo_prepare_bundle, ph_zenodo_check_record

Preprint PDF, source zip, code and data zip, deposit-format metadata and an upload walkthrough. After you publish, it diffs the live record against the plan.

Ledger and QA

ph_paper_numbers, ph_acceptance_checklist

Every quotable number is written to paper_numbers.json. The checklist reports the spec's §3 acceptance items.
