The list
The list of worlds is the NASA Exoplanet Archive at Caltech/IPAC, table of composite parameters, read on : worlds. Exoplanet is not affiliated with NASA, Caltech or IPAC, and the name of a world is the name the catalogue gives it.
Each value on a sheet is either published, estimated by the archive, or absent from the catalogue, and it is labelled as such. Nothing is invented to fill a gap.
