Criteria for inclusion in the catalog
The basic criterion is the mass limit: 60 Jupiter mass.
The former standard limits were13 Jupiter mass, based on the deuterium burning limit, and 30 Jupitter mass, based on formation scenario. However, the mass-density-radius distribution (Hatzes & Rauer, 2015) shows a clear difference between giant planets and stars at 60 Jupier mass.
An additional difficulty comes from the uncertainty in the mass value. We therefore allow for a 1 sigma uncertainty and chose 60 Mjup + 1 sigma as an upper mass limit.
We thus finally include planets with masses < 60 Jup up to 1 sigma
Are included planet detections published or submitted to professional journals or announced by professional astronomers in professional conferences.
There are 4 categories of planets, Confirmed, Candidate, Retracted and Controversial. A planet is considered as Confirmed if it is claimed unambiguously in an accepted paper or a professional conference.
