Pearsons χ² results of line ratios predicted by RADEX modeling and the observed ratio for all detected E-type CH₃OH lines of the three regions (left: A, middle: B, right: F). The color-scales are chosen such that lighter color indicates lower χ² values and better agreement with observed line ratio and models. Densities are well fitted with values of 2 × 10⁷ cm^-3 for region “A”, > 3 × 10⁸ cm^-3 for region “B” and 4 × 10⁷ cm^-3 for region “F”,
