Comparison between the kinetic temperatures derived from pyRADEX+MCMC modeling and using the p–H₂CO integrated line intensities ratios R₁ (top panel) and R₂ (middle panel). Bottom panel: comparison of the kinetic temperatures derived from R₁ and R₂. The LTE temperature uncertainties are from uncertainties in the integrated intensities of the observed p–H₂CO lines. The dashed black lines indicate a slope of unity.
