Detuning of the classical standing wave field with the atomic transition plays an important role in the characterization of the peaks present in Autler-Townes spontaneous spectrum of a three-level atom. We investigate how this detuning effects the position distribution of the atom and show that we gain a precision in position information of the single atom inside the standing wave field by introducing the detuning between the atomic transition frequency and the frequency of the driving field in the upper-level coupling case. We also show that this precision in localization of an atom is not observed in the lower-level coupling case, due to the absence of the quantum interference.
