Notes. Fit parameters when fitting a linear relation to binned line emission as a function of N2H+ emission in log space, binned 12CO line ratios as a function of N2H+/CO, and binned 12CO line ratios as a function of N2H+ intensity. We provide slopes and offsets of linear trends applied to the logarithmic binned values for the full FoV, and provide slopes when fitting binned values obtained in individual environments. For the full FoV, we provide the average scatter after subtracting the best fit from the data (Sect. 3.2).
