For nearly 50 years, the Burg/Andersen (BA) maximum‐entropy (ME) deconvolution procedure has been used to sharpen, and therefore accentuate, weak features in spectra, optical and otherwise. It is shown that the BA procedure can be further enhanced to yield even sharper features. Using this approach, the authors establish the existence of the biexciton in ellipsometric data of monolayer WS2 at 50 K, whereas differentiation and standard BA analysis cannot.
