 \caption{Best fit values of angular distribution width parameter $\Delta \Theta$ for 
DW flares and of $\alpha$/p for DW and PAS($\lambda=30$) flares 
for combined fits of the $^{12}$C and $^{16}$O lines.
Spectral index of accelerated particles $s=4.0$; values in parenthesis are for  
$s=3.0$. The values of $\alpha$/p and $\Delta \Theta$ 
for $s=3.5$ are generally between those of $s=3.0$ and $s=4.0$.
