It is generally assumed that the temperature is rapidly equilibrated along the magnetic field lines inside the island, so that radial transport is effectively short-circuited across the islands, decreasing the effective size of the main plasma.

However, is is possible to qualify this statement somewhat by taking into account the ratio between parallel and parpendicular transport within an island.
