Top left: extinction-corrected H₂ rotational lines vs. Kristensen et al. (2023) shock models. The best model with ${\chi }_{\mathrm{m}\mathrm{i}\mathrm{n}}^2$ is shown in solid dark gray lines with its parameters displayed. The selected models with ${\chi }^2-{\chi }_{\mathrm{m}\mathrm{i}\mathrm{n}}^2<10$ are overplotted with light gray lines. Subsequent panels show the histogram distribution of key model parameters (shock type, magnetic scaling parameter, shock velocity, external UV field, and pre-shock density) that determine the prevailing shock condition.
