The model atoms for the iron-group elements (here Ca - Ni) can individually be constructed
for a single species or for a group of elements combined in a so-called generic
model atom. For details see Rauch & Deetjen (2003).
The default solar element abundances are taken from
Scott et al.(2015).
They may be used, e.g., to calculate a generic model atom (see above) with elements in solar abundance relation.
