\caption{Changes ($\Delta$) in the derived N~abundance caused by errors in 
model atmosphere parameters for HD~122563, a cool star, and CS~22948-066 
(hotter). A is the adopted model; B, C, and D vary log $g$, \vt, and \Teff\ 
individually as shown, while in model~E, log $g$ and \vt\ have been re-adjusted 
for consistency with the lower \Teff\  (see also Paper~V, Tables~6 and~7).}
