a Only lines with intensity uncertainties lower than 40% have been considered (see text).
b Corrected from NLTE effects (see text).
c Recombination coefficients for intermediate coupling (Liu et al. 1995).
d Deblended from [S  II] $\lambda$4076.35 line, using the theoretical strength ratio $\lambda$4075.86/$\lambda$4072.15.
e Deblended from [S  II] $\lambda$4068.60 by assuming the theoretical ratio C  III $\lambda$4067.94/$\lambda$4068.91.
