In (f), green denotes the voids/cracks connected directly to the outer surface of the annulus; blue identifies closed voids/cracks that do not touch the inner or outer surface of the annulus; yellow identifies voids/cracks touching the inner surface of the annulus; and red identifies voids/cracks touching the inner and outer surfaces.
