Each catalog will be discussed in Section 2. but it is worth saying that they are different because each catalog considers different criteria to include a new planet in its collection. These criteria are usually based on the physical properties of the planet or statistical th Exo-MerCat: a merged exoplanet catalog with Virtual Observatory connection. resholds.For example, different catalogs use different mass boundaries or include candidate targets in addition to planets described in peer-review paExo-MerCat: a merged exoplanet catalog with Virtual Observatory connection.
