Abstract
The principle of superposition which was derived in [14] appears here following the description of modified reflection factors ℜ(d,H) for mirror sources because that principle also delivers such a reflection factor (Instead of the meaningless denomination “third principle of superposition” used in [14] and in [9, Sect. B.10] we here apply the name “hard-soft superposition” which at least indicates the fundamentals of that principle).
