# circular error

An accuracy figure representing the stated percentage of probability that any point expressed as a function of two linear components (e.g., horizontal position) will be within the given figure. Circular error probability (CEP 50%), and CE (90%) are used commonly. A horizontal measurement on the ground, in feet or meters, defining a radius of a circle, within which an object of known coordinates should be found on an image. The CE value should have some measure of probability (P) associated with it. For example, a CE of 100 m and .9 P, means that 90% of the time the object will fall within a circle having a radius of 100 m. Circular error is normally used in armament delivery results.
