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 $c_1 = κL$, and $c_2 = κΩσ^2$, 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 $c_3 = σΩ$, where $σ$ denotes the half width of a Gaussian window function specifying the field-detector interaction, and show agreement with earlier work the large $c_3$ limit.
