\caption{Spectral fits of the South Blob (circle of radius 200~arcsec),
VSSR (circle of radius 150~arcsec) and Impact regions, with two different
models. Abundances are in solar units and error bars are~1$\sigma$.
Values of~$N_{\rm H}$  are in units of $10^{20}~\rm cm^{-2}$.\label{tbl:specfitsreg}}
