*Cloudy produced spectrum of a model of the environment in the outer region of
Perseus core. The figure shows resolved fine-structure doublets, using a spectral resolution of R = 0.25 eV. The model has a log column density of 24.*
*Cloudy's simulation of the outer region of the
Perseus galaxy cluster. The figure shows resolved fine-structure one-electron doublets
such as Fe XXVI. A spectral resolution of R = 0.25 eV and a log column density of 24 were
used. J-splitting of the nP - 1S lines is a major improvement in C24, as described in
