About 45% of the R_PAH measurements are overestimated by more than 10% when measured in the MUSE-based apertures for H II regions compared to the values in their centers. Panel (a) shows the probability distribution of R_PAH measured in different circular apertures for the same sample of H II regions related to the value of R_PAH measured at the local peaks of Hα brightness within the H II region. Panel b demonstrate how such ratios change for different Hα luminosity bins. The different colors correspond to different outer radii of the circular aperture.
