Distribution of total counts for the spectra in the two datasets. The blue histogram represents the dataset based on the reference spectrum with approximately 2 × 10³ total counts (Dataset-short). In comparison, the orange histogram corresponds to the dataset based on the reference spectrum with approximately 2 × 10⁴ total counts (Dataset- long). Both distributions illustrate the variability in total counts due to the range of parameters used in the simulations. Vertical dashed lines show the position of the two reference spectra.
