Model band structures are constructed for Rh, Pd, Ag, Ir, Pt, and Au using a combined interpolation scheme. Spin-orbit coupling and other relativistic corrections are included. The energy distributions of the joint densities of states (EDJDOS) are calculated using quadratic interpolation and a Monte Carlo sampling of $k$ space. Extensive numerical results are presented. A strong resemblance is found between the variation of the profile of the EDJDOS with photon energy and the profile changes seen in experimental photoemission spectra. This has been used to make empirical adjustments to the widths of the $d$ bands in some of the model band structures.
