Table 4:

Element source abundances for Model III-C and comparison with HEAO-3 results.
Z Element $ 10^{22}\times q_Z$      HEAO-3
     (m3 s GeV/n)-1 (Engelmann et al.)
6 C $148.5 \pm 3. $ $164.9 \pm 4.7 $
7 N $ 8.1 \pm 0.6 $ $ 9.9 \pm 3.4 $
8 O $185. \pm 3. $ $204. \pm 2.2 $
9 F $ 3.67~\pm 0.05 $ $ 3.67~\pm 0.05 $
10 Ne $ 24.1 \pm 0.4 $ $22.5 \pm 1.3 $
11 Na $ 1.88 \pm 0.08 $ $ 1.25 \pm 0.5 $
12 Mg $ 40.3 \pm 0.6 $ $ 40.3 \pm 1.0 $
13 Al $ 3.69~\pm 0.1 $ $ 3.02 \pm 0.6 $
14 Si $ {\bf 38.8} \pm 0.5 $ $ {\bf 38.8} \pm 0.5 $
Note 3: Isotopic fractions of elements qi/qZ are fixed to Solar System ones (Lodders 2003) and $q_Z\equiv\sum_{i=\rm isot.} q_i$. The best-fit value is obtained from the best-fit model (on B/C), where source abundances were rescaled to match HEAO-3 data at 10.6 GeV/n. The uncertainty in qZ originates from the same rescaling, but arising from all combinations of parameters satisfying the 68% CL on the $\chi ^2$ distribution. For HEAO-3, the numbers are taken from Table 7 of Engelmann et al. (1990), and have been rescaled to $q_Z({\rm Si})=38.8\times10^{-22}$ (m3 s GeV/n)-1 (boldface) to ease the comparison.
