Thermal states of light are widely used in quantum optics for testing of various quantum phenomena. Particularly, they can be utilized for characterization of photon creation and photon annihilation operations. During the last decade the problem of photon subtraction from multimode quantum states has become of much significance. Therefore in this paper we present a technique for statistical parameter estimation of multimode multiphoton-subtracted thermal states of light, which can be used for the multimode photon annihilation test.
