Fig. 1


Absorption measure distribution for the warm absorber of NGC 3783 using the solar chemical abundances measured by Asplund (2009). Top panel: differential form of the AMD. In the bottom panel it is integrated up to the total column density (see Eq. (1)). A scale in ξ and in temperature T are provided with the relation T(ξ) being obtained from the xstar computations of the fractional ionic abundances (see text).
