PAH to total dust mass fraction for the 38 galaxies with ALMA 1.1 mm detection (from the ASPECS survey; Walter et al. 2016). Five of them also have 3 mm detections. The axes show the derived q_PAH including and excluding the ALMA data points. Median of the q_PAH values without ALMA to those with ALMA data is 0.95, completely within the q_PAH uncertainty, indicating the q_PAH values inferred based on UV-to-MIRI data alone are robust.
