Kaldra IV

Kaldra IV was the inhabited fourth planet in its star system.

The USS Enterprise-D was transporting three Ullian telepathic historians to this planet in 2368, whose inhabitants they hoped to add to their library of individual memories. However, the Enterprise was diverted to the Ullian homeworld after Jev's perpetration of telepathic memory invasion was discovered. (TNG: "Violations")

In 2376, the location of Kaldra IV was labeled on a star chart in astrometrics on USS Voyager in 2376. (VOY: "Child's Play", display graphics)

According to StarTrek.com, Kaldra IV was located in Sector 22139. [1](X)
Both Star Trek: Star Charts ("United Federation of Planets I") and the Star Trek Encyclopedia, 4th ed., vol. 1, p. 400 identified Kaldra IV as a Federation planet.
