Distributions of AME parameters in the source sample. Each panel includes an inset in the top-right showing the median (black) and smallest (green) 1σ uncertainties for that parameter among all sources. For A_AME, the median and smallest uncertainties are 0.6 Jy and 0.1 Jy, respectively; the corresponding uncertainty bars are not visually discernible, as their horizontal caps are unresolved at the adopted linewidth. A best-fit Gaussian is drawn as a dashed red line on the ν_AME and W_AME distributions. The red shaded region in the W_AME panel highlights the range of effective widths predicted by single-phase SPDUST2 and SPYDUST templates (see Table 2).
