****   Existence is certain, and properties are at least fairly explored.
***   Existence ranges from very likely to certain, but further confirmation is desirable and/or quantum numbers, branching fractions, etc. are not well determined.
**   Evidence of existence is only fair.
*   Evidence of existence is poor.
