Regarding Rigel, and the odd dialogue on the star system of that name in "Broken Bow"... What does the novelverse say about Beta Rigel or its relationship to the more familiar Rigel in the Orion constellation, exactly?
There was a typo in "Star Trek Star Charts" that was intended to clarify the Rigel of ENT and the distant Rigel of "The Cage":
The Rigel Colonies' star, Beta Rigel, as depicted in ENT, was considered by that book to be different to "true" Rigel (ie. Beta Orionis A). The seventh planet of Beta Orionis A is home to the Kaylar.
