Habitability flag is a rough heuristic — it marks worlds that are small (≤1.8 Earth radii) and temperate (equilibrium temp 180–320 K). It is an illustrative estimate of where liquid water could exist, not a scientific determination that a planet is habitable. Equilibrium temperature ignores atmosphere. "—" means the value isn't measured (common for planets found by radial velocity, which don't reveal size).
