Information on this system was derived from the episodes, from the reference works Star Trek: Star Charts and Stellar Cartography: The Starfleet Reference Library, and from real world sources. The reference works were used extensively in the creation of star charts seen in Star Trek: Discovery, Star Trek: Picard, Star Trek: Strange New Worlds, Star Trek: Prodigy, Star Trek: Lower Decks, and Star Trek: Starfleet Academy. The real-world information added to the article was current as of 2026.
