German term or phrase: Kreisring

Context:

"Um g(r) rechnerisch zu bestimmen (vgl. Abb. 2) wählt man zunächst ein beliebiges aber festes Differential dr. Dann zählt man ausgehend von einem Objekt für alle Werte von r bis zu einem festgelegten Maximalradius alle weiteren Objekte in einem Kreisring mit Radius [r, r + dr]."

Re. radial pair correlation. I'm a bit thrown by the use of "in einem Kreisring mit Radius ..." vs. "bis zu einem festgelegten Maximalradius"

Draft translation:

In order to be able to calculate g(r) (see Fig. 2) it is first necessary to choose any fixed differential dr, before then counting the number of objects within a circular ring of radius [r, r + dr] around r out to a predefined maximum radius, starting from any one of these objects.

"...a bit thrown by the use of "in einem Kreisring mit Radius ..." vs. "bis zu einem festgelegten Maximalradius":
A doughnut has two radiuses, the inner + the outer one.
The inner radius is r. The outer outer one is r plus the differential dr...
