Dwell Zone

Region around a star wherein shield and jump drive can regenerate after exiting jump.

It extends as a thin disc about 70 astronomical units around a Sol like star.

Determining the angle, offset, and thickness of the disc makes estimating stellar coordinates difficult from a distance.

An exploration ship can precisely measure the dwell zone it is in.

At a distance of 7 light years, reliability drops to 75 to 90%.
