Transit Lab
Public light curves retrieved from MAST, detrended with a Savitzky-Golay filter, folded on the published ephemeris and fitted with a trapezoid. Every fit is checked against the published depth before it is called validated.
HD 209458 b
The first transiting exoplanet ever detected; bright (Tmag 7.1) with a deep transit.
Fit vs. published
This fit is consistent with the published depth within a factor of 1.6 and is treated as validated.
Why these targets, not the top candidates
Validation of the transit pipeline against planets whose depths are independently known. These are bright hot Jupiters and sub-Neptunes chosen for signal strength, NOT Earth-2.0 candidates, and they are excluded from the candidate ranking.
Fitted depths run consistently below published values. This is a known systematic of the Savitzky-Golay detrending step, which absorbs a little of the transit even with its window forced to at least three times the transit duration. Depths from this pipeline are approximate and biased slightly low; published limb-darkened values take precedence.
