Examples of merger times measured in our simulations, τmer, as a function of the initial circularity of the orbit, є, showing the effect of varying the orbital energy, rcir,p, while keeping all other parameters unchanged. This plot shows results for equal-mass mergers of spiral galaxies with the modal value of the spin parameter (λ = 0.04). Open squares are used for mergers with rcir,p = 2.0, while open circles identify rcir,p = 4/3 mergers. Data points are shown with different offsets around the true values of є for clarity.
