We study theoretically the single photon ionization of atomic targets by an attosecond pulse train assisted by an infrared laser field. We employ a non-pertubative model that under certain approximations gives closed form expressions for the observables of the reaction. Interestingly, this analytical expressions allow us to interpret the angular distributions of photoelectrons as two-center interferences where the separation between the virtual emitters is governed by the infrared laser field.
