Spearman correlation coefficients between A_AME and individual frequency maps. Tracers are shown on the right, where CO denotes the 1–0 CO transition map by Ghosh et al. (2024) and S_peak, d is the flux density at the peak of the thermal dust emission fit. In both cases, τ₃₅₃ refers to the angular area-corrected optical depth τ₃₅₃ ⋅ Ω. Hollow points denote frequencies that are excluded from the SED fitting. The 100 and 217 GHz bands are CO-subtracted.
