slit centered on A crosses  B in its northern part.\\
$^{b}$ As the line is affected by blending, an additional spectrum was obtained 
with a $FWHM = 1.1$~{\AA}
through the same slit width   giving an  [Ar IV] $\lambda$4711/[Ar IV] 
$\lambda$4711+HeI $\lambda$4713 ratio of 0.47.\\
$^{abs}$  Since [SIII]$\lambda$9532 is  affected by telluric absorption its intensity 
has been estimated from the intensity of  $\lambda$9069 and taking into account  that  the A value of $\lambda9532 =  0.0576$ and that the A value of  $\lambda9069 =
0.0221$ (Mendoza \cite{Mendoza83}).\\
$^{u}$   In units of 10$^{-12}$~ergs~s$^{-1}$~cm$^{-2}$,  the equivalent width of H($\beta$) is 415~{\AA}.\\
$^{91,}$ $^{97}$  1991 and 1997 observations.
