With a lower limit on Nm0/Na0 of 2, as discussed earlier, the true value of Su48 according to Fig. 6 lies between — and This prediction, however, takes no account of uncertainties in other model parameters. The curves in Fig. 6 refer to models consistent with a relative C/C ratio in the surface layer, Rm/R#, of in 1954. If instead we adopt the lower limit of , we obtain the results shown in Fig. 7. For the same range of Nm0/Na0, the Suess effect is more negative by about On the other hand, for a given value of Nm0/Na0, the range in growth factor remains.
