We consider acceleration-assisted entanglement harvesting as evidenced in correlations between two accelerating Unruh detectors coupled to a scalar field. We elaborate on earlier studies, which in a stationary phase approximation calculated the entanglement dependence on two parameters c1 = κL, and c2 = κΩσ2, where κ describes the detector's acceleration, L their separation and Ω the energy splitting in a pair of two state Unruh detectors. Here, we go beyond the stationary phase approximation by performing a numerical calculation of entanglement harvesting, allowing us to present the dependence on c3 = σΩ, where σ denotes the half width of a Gaussian window function specifying the field-detector interaction, and show agreement with earlier work the large c3 limit.
