Husimi Q -functions are the only functions from the class of Cohen quasi-distributions on phase space that after scaling transformation ( q , p )→(λ q , λ p ) remain in the same class when the modulus of the scaling parameter is smaller than unity and so, in this case, describe a physical state. We found the Wigner functions and symplectic tomograms of such states. We applied the obtained general results to the Fock states of the harmonic oscillator.
