Averaged final mass fraction ratios V/Mn and Ti/Mn in the optical phase, as a function of the initial neutron excess. The point types and colors in these plots refer to the time at which the ratios are drawn, blue solid circles are calculated at day 15, whereas red solid squares belong to day 30. The ranges of the parameters τ_rise, τ, and X(¹²C) are as in Fig. 9. Left: abundance ratio of vanadium to manganese. The ratios are fit by power-law functions, namely M(V)/M(Mn) = 0.018/η^0.42 for the points at day 15, and M(V)/M(Mn) = 0.026/η^0.29 for the points at day 30. Right: abundance ratio of titanium to manganese. In this case, the points belonging to days 15 and 30 can be reasonably fit by a single function, although it cannot be a simple power law. The fit function shown is, M(Ti)/M(Mn) = exp⁽−6.45−1.1lnη−0.043ln²η⁾.
