Table 3: Electron density derived from Mg VIII lines ratios. The 315.015 Å and 335.231 Å line intensities have been corrected assuming that they are affected by blendings contributing 50% and 20% of the observed intensity, respectively. C is the correction factor applied to the line ratio to take blending into account.
