Delay time distribution assuming the γ-algorithm for the CE with γ = 1.75. Different lines correspond to the delay time distributions that result from four different approaches described in Sect. 3, all for the γ-prescription. The dot-dashed line shows the result of the Islands selection method, the three other linestyles correspond to the retention efficiencies as in Fig. 3. Note that for the retention efficiency of Y10 no SD binaries evolve into a SNeIa.
