(1977). For each line, we indicate: the observed intensities $I_{\rm obs}$ ; the lower and upper level index corresponding to Table 2; the theoretical wavelength. The large disagreements at 4 $^{\prime \prime }$ could be due to blending and to calibration errors at the longer wavelengths.

The large disagreement for the 2-5 line is probably due to blending and to calibration errors at the longer wavelengths.

(2001) calibration with the newly identified 6-18 592.6 Å line. Note the excellent agreement. Densities from ions emitted at similar temperatures are in the range log $N_{\rm e}$ = 8.7-8.8 cm^-3.

The agreement between our present model and the observations is excellent. The curves also indicate an electron density log $N_{\rm e}$ = 8.8 cm^-3, in excellent agreement with the values derived from other ions.
