Experimental relative photometry. No transit confirmation; conditional errors do not include all systematic effects.

Calibration/orientation segment b21df953

DifferentialEnsemble1.0210.9950.02 — 0.12 hours since the first recorded header start · exposure midpoints
Saved relative measurements; gaps are retained.

Single event: not_run. Periodic: not enough suitable data.

Calibration/orientation segment 1c4b2e62

DifferentialEnsemble1.0870.95530.16 — 2.14 hours since the first recorded header start · exposure midpoints
Saved relative measurements; gaps are retained.

Single event: searched. Periodic: At least 12 hours baseline for declared >=6 hour periods; three sampled events required.
