We discuss a system with two discrete levels embedded in one continuum, which, after Fano diagonalization, gives a double Fano profile with two zeros. The second zero, which is located between the two levels, does not disappear even when the asymmetry parameter q goes to infinity. The spectrum of photoelectrons from such a system is calculated for any strength of the exciting field.
