Summation of the spectra of all partially resolved transition arrays in a supertransition array

It is shown that the contributions of all partially resolved transition arrays (PRTAs) to the spectrum of a supertransition array (STA) may be summed by an efficient analytical method. The method is similar to the configurationally resolved super transition array method [G. Hazak and Y. Kurzweil, High Energy Density Phys. 8, 290 (2012)] and avoids the Gaussianity assumption of the partially resolved super transition arrays method [B. G. Wilson, C. A. Iglesias, and M. H. Chen High Energy Density Phys. 14, 67 (2015)], thus yielding an STA spectrum which is resolved down to the PRTA level.
