Reply to "Comment on 'Limits of the measurability of the local quantum electromagnetic field amplitude'"

We argue that the criticism by Hnizdo [preceding Comment, Phys. Rev. A 60, 4212 (1999)] of the results obtained by Compagno and Persico [Phys. Rev. A 57, 1595 (1998)] on the theory of measurement of the amplitude of the quantum electromagnetic field is unfounded. By a simple and direct approach we show that the quantities evaluated by Hnizdo in his Comment are incorrect and we present the correct results. [S1050-2947(99)05911-9].
