13. Our results show that the variance signal drastically depends on the detection wavelength as expected from Eq. (4). Reference [4] uses a term of second order in ω in the description of the detection process that is the same as the one we used in the relevant wavelength range. In the experimental part of Ref. [4], however, no reference to a detection wavelength is given, though the amplitude of the oscillations and hence the determined squeezing amplitude should strongly depend on it.
