  The multiphoton-subtracted thermal states are an interesting example of
quantum states of light which are both classical and non-Gaussian. All the
properties of such states can be described by just two parameters of
compound-Poisson photon number distribution. The non-Gaussianity dependency on
these parameters has been calculated numerically and analytically. The loss of
non-Gaussianity during the optical damping has been also studied
experimentally.
