Maps of physical parameters constructed with the PDRTPY routine (Pound & Wolfire 2022) via spaxel-by-spaxel two-linear-component fit of the excitation diagrams: T_warm map of the warm temperature fit component (upper right); T_hot map of the hot temperature fit component (upper left); H₂ ortho-to-para ratio (OPR) map (bottom left); surface-mass map (bottom right). The maps were convolved to the resolution of the H₂ 0–0 S(1) map and reprojected to the spaxel grid of CH2. The FoV is limited to the spaxel coverage of the smallest map. The H₂ 0–0 S(6) and S(8) maps were excluded due to the high number of flagged spaxels.
