Notes.
OSALD fits of the ROIII and [Ar IV] doublet ratios assuming a density distribution which extends from 102 cm−3 up to the cut-off density ncut. The weight applied to the emissivities follows a density power-law of index ϵ = +0.6.
Weighted average plasma density taking into account the increase of the covering factor with density.
Temperature difference between 
of the power-law density case and 
of the single density case of Table 2.
