In the article we obtained results that are specific for the parameters of the atom interferometer and test mass’ shape and trajectory. We think for the each case one should generate one figure 3 to answer all questions regarding the validity and role of different parts of the phase and approximate expressions for them. Instead of using a lot of dashed curves, we decided to use a panel of figures. Although each plot is difficult to read at “normal” magnification, the online reader can easily magnify any plot when accessing the article in PDF format. We have added a note to this effect.
The treatment involves quantum corrections which are treated by calculating the Wigner representation of the density matrix and I am not aware of the use of such an extensive use of Wigner representation to describe atom interferometry experiments.
