The bound states of three-body atomic or molecular systems are usually calculated assuming the three particles interacting through Coulomb potentials. While this is correct for systems placed in a vacuum, when they are placed in an external environment the potentials change. As a result, the energy levels and other properties of the considered system change considerably. We provide analytical fits of the energy E and some mean values <rpij> as a function of the screening parameter.
