Parameters used in the MCMC analysis coupled with the radiative transfer algorithm LOC.

Parameter	Range	Value
k_n	1.3−2.7	${2.11}_{- 0.06}^{+ 0.06}$ $2.11_{-0.06}^{+0.06}$
X(N₂H⁺)/10⁻¹⁰	10⁻²−10⁺²	${1.00}_{- 0.05}^{+ 0.07}$ $1.00_{-0.05}^{+0.07}$
k_{T_K}	1.0 − 1.8	${1.39}_{- 0.01}^{+ 0.01}$ $1.39_{-0.01}^{+0.01}$
R_D	0.2 − 0.8	${0.50}_{- 0.01}^{+ 0.01}$ $0.50_{-0.01}^{+0.01}$

Notes. For each free parameter explored in the MCMC analysis, the second column reports the range explored (prior probability distribution). The third column states the median value obtained in the posterior distribution along with the 0.16 and 0.84 percentiles as the uncertainty range.
