Remark: What the result contributes

The exact equality, the treatment of all angular transitions, and the holonomy criterion for disappearance of the strictly diffractive relation are the mathematical release of this companion. Cone diffraction and quotient image methods are established subjects CheegerTaylorI,CheegerTaylorII,MelroseWunsch,Yang; the present paper does not claim that these phenomena originate in the Enter framework.
