Observed column densities of individual ionic species, Ni,obs, in the warm absorber of NGC 3783 compared to the model results. The five figures correspond to different values of the ionization parameter, ξtot, with their corresponding total hydrogen-equivalent column densities (see Table 1). The observed data (black squares) carry error bars, the models are indicated by blue pentagons and red hexagons for the hot and cold solution, respectively. Top-left: ξtot = 2000 erg cm s-1, top-right: ξtot = 4000 erg cm s-1, middle-left: ξtot = 8000 erg cm s-1, middle-right: ξtot = 16 000 erg cm s-1, bottom-left: ξtot = 20 000 erg cm s-1. Arabic ion numbers are equivalent to roman numerals.
