Distribution of column density ratio N_ELGM/N₂₀₀ for the six studied ions, for a sample of sightlines covering the simulated sky of simulation 17_11 uniformly. Purple histograms correspond to distributions for all material within and outside the CGM of the MW candidate, while green histograms show the distributions after material with disc-like motion within R₂₀₀ has been filtered out using the method described in Sect. 3.2. The fraction of sightlines with column density ratio N_ELGM/N₂₀₀ > 1 (grey shaded area), noted as f_ELGM, is indicated in all panels for each histogram.
