    • The decay-associated spectra contain the preexponential factors a of the exponential functions that were used for the global fit analysis. They are wavelength dependent and are calculated using the following expression: (Formula presented) where n is equal to the number of exponential functions used for the global fit and ISS(λ) corresponds to the intensity of the steady-state emission, and α/λ) are the preexponential factors obtained by the global fit.
