A transit search where a panel of independent reviewers marks dips in blind-coded light curves, consensus is skill-weighted, and every candidate keeps its provenance. Built to follow the Planet Hunters CHEOPS workflow.
Thresholds, weights and every input are written to manifest.json, so a result can be rerun exactly.
Passed candidates are the catalogue. Rejected and flagged events are kept on purpose, so a reader can see what the vetting decided and why.
Every reviewer's answer for every blind-coded subject. Disagreement is kept visible, because it is where the consensus is earned.

They could be transits, but the scatter is high and increases in the later part of the light curve, so they c |
| claude-skeptic | potential planet | 1344.200–1344.340, 1350.380–1350.510 | Two short, flat-bottomed dips of about 300 ppm at ~1344.27 and ~1350.45 (spacing ~6.2 d) have matching depth and duration, as expected for a periodic transit. Neither shows a V shape, a secondary eclipse, a ramp or a step, but the data around the second dip is |

Run runs/tess-pi-men-s1 (TESS SPOC sector 1, 10-minute bins), run on the current code (scripts/rerun_pi_men.py), with the limb-darkened fit (src/setuhq/transitfit.py). 5 of 5 predicted epochs are recovered by the panel. Limb darkening: Claret 2017 TESS quadratic u₁ = 0.341, u₂ = 0.224 for the TIC's Teff 5992 K and log g 4.36. Reference: NASA Exoplanet Archive, table ps, pl_name = 'pi Men c', fetched 2026-10-19 (docs/results/pi_men_reference.json).
Two lines. **Free**: depth, T14 and k are robust; b, a/R★ and ρ★ are degenerate with five TESS transits, so b is an upper limit when its 1σ set reaches 0 and ρ★ is a range. **With the TIC density prior** (a Gaussian on ρ★, 1.023 ± 0.199 g/cm³): b, a/R★ and T23/T14, to compare with Huang's b = 0.59. Like-for-like comparisons lead: k and T14.

¹ Depth definitions differ: SetuHQ's is the limb-darkened model's depth at mid-transit; the archive's pl_trandep is the published transit depth as each paper defines it. Compare k and T14 first.
Errors are conservative: the covariance at the best fit (scaled by √χ²ᵣ when above 1) added in quadrature to the spread along the impact-parameter profile (Δχ² ≤ 1), which overlap.
The box measure used before (the mean flux over the panel's marked window): depth 243 ppm, duration 1.90 h, ratios **0.81** and **0.64** against Huang 2018 (0.91 and 0.64 against the archive default row the README used to cite).
ρ★ check (free fit): the transit density against the TIC's 1.023 g/cm³ (consistent within the illustrative 0.3–3 band at 3σ). V-shape test: U-shaped (not grazing).
| subject | epochs | P (d) | depth (ppm) | T14 (h) | b | ρ★ (g/cm³), 1σ range |
|---|---|---|---|---|---|---|
| tess-fa3483ce6f83 | 3 | 6.2681 | 294 ± 10 | 3.17 ± 0.25 | b < 0.94 (1σ) | 0.091–2.249 |

Depth is the model's mid-transit depth; errors are conservative, as above. Each subject's fit frees the period near that subject's BLS period.
Recorded by scripts/validate_known_planets.py at commit 0f6dbdc from a live query of the archive's default row then. Its timing columns stand; its depth and duration ratios came from the box measure and are superseded by the fit above.

Completeness is the fraction of injected transits recovered as a vetted candidate, with the consensus centred within half a transit duration of the injection.
