The catalogue is the visible tip
Finding Earth 2.0 reconstructs the selection that shaped Kepler DR25, then asks which intrinsic population is consistent with the signals that survived.

What the analysis found
Detection losses dominate near an Earth-like orbit
The difference between a catalogue count and a population estimate is the missing part of the survey: geometric transits that never occur, phases that were not observed, signals the pipeline misses, candidates rejected by vetting, and remaining false-alarm uncertainty. Reversing that chain produces a broad posterior rather than a single corrected count.

These counts describe detected and reliability-adjusted signals in the declared DR25 sample. They retain the imprint of transit geometry, observing windows, pipeline recovery and vetting.
