Table 8: Results of neutron exposures. Columns 2 and 3 correspond to results of the fittings to the theoretical predictions of Malaney (1987a) and Cols. 4 to 7 to those of Malaney (1987b). $S\sp 2$(u), $S\sp 2$(e8), $S\sp 2$(e12) are the fit quality, respectively, for single exposure, exponential exposure under neutron density 10$\sp 8$ cm$\sp {-3}$, and exponential exposure under neutron density 10$\sp {12}$ cm$\sp {-3}$. $\tau _{\rm o}^{\rm a}$, $\tau _{\rm o}^{\rm b}$, and $\tau _{\rm o}^{\rm c}$ are the mean distributions of neutron exposure corresponding to $S\sp 2$(u), $S\sp 2$(e8), and $S\sp 2$(e12), respectively. $\tau _{\rm o}$(f) and $n\sb {\rm n}$ are results corresponding to smaller $S\sp 2$. Column 10 shows if the best fit corresponds to exponential (exp) or single (sing) exposure. Columns 11 to 13 correspond to the results of the fit of $\sigma N$ curves, with $\chi _{\rm red}$ as the quality of the fit. Numbers in parenthesis are errors in last decimals and were estimated directly from the fittings. The uncertainties on $\tau _{\rm o}^{\rm a}$, $\tau _{\rm o}^{\rm b}$, and  $\tau _{\rm o}^{\rm c}$ were estimated in 0.1 mb$\sp {-1}$. For all cases, $\tau _{\rm o}$ is given in mb$\sp {-1}$.
