Candidates

Be the vetter.

Each card is a real dip that one of SetuHQ's example runs stored. Look at its light curve, its fold, its odd and even depths and its depth half an orbit later, then call it: pass, flag or reject. Then see what the vetting decided, and why.

A learning exercise, not a contribution to the science. Your answers stay in this browser and are not collected or sent anywhere; the dips are stored dips from SetuHQ's example runs, already decided by its vetting.

What to look for
  • Light curve: a dip with a flat floor and sharp edges is transit-like; a V shape or a lone spike is suspect.
  • Fold: a real periodic dip lines up at one phase.
  • Odd / even: different depths on alternate dips point to an eclipsing binary at twice the period.
  • Secondary: a dip at phase 0.5 points to a second star being eclipsed.

Pass: a candidate (never a confirmed planet). Flag: open, needs a closer look. Reject: not a candidate.

Show what the vetting decided

Vetting: candidate, unconfirmed. Passed every vetting check. Its period matches pi Men c in the stored archive cross-match (ΔP 0.08%): a known planet, recovered, not a discovery. The dip itself stays a candidate, unconfirmed as an independent detection.

  • Every vetting check measured and passing.

This was pi Men, dip 2 (6.27 d). Panel score 1.00, marked by 5 reviewers.

Vetting: rejected by vetting, not a candidate. Rejected by vetting: SNR 6.7 (rule ≥ 7); ephemeris off (rule on ephemeris). A single dip with no BLS period of its own. Marked by 3 of 3 Probes and 0 of 2 Sentinels. Not a candidate.

  • SNR: failed. Dip is strong enough to trust.
  • odd / even (signal-level): not measured. Alternating depths would mean a binary at twice the period. Measured once per BLS ephemeris over all its epochs in the subject, not per dip.
  • secondary eclipse (signal-level): not measured. A dip at phase 0.5 would mean an eclipsing binary. Measured once per BLS ephemeris at phase 0.5 in the subject, not per dip.
  • ephemeris: failed. Not explained by the strong periodic signal of its star.
  • flag: low_snr
