Parameters used for the MCMC RADEX exploration.

Parameter	C₂H	o-c-C₃H₂	HC₃N
T_kin (K)	7.3, [5 − 10]	7.8, [5 − 20]	6.1, [5 − 11]
$n_{p - H_{2}} ({cm}^{- 3})$ ${n_{{\rm{p}} - {{\rm{H}}_2}}}\left( {{\rm{c}}{{\rm{m}}^{ - 3}}} \right)$	10⁵, [10³ − 10⁶]	10⁵, [10³ − 10⁶]	10⁵, [10³ − 10⁶]
N_tot (cm⁻²)	1.83 × 10¹⁴, [10¹³ − 10¹⁵]	3.44 × 10¹², [10¹¹ − 10¹³]	3.25 × 10¹³, [10¹² − 10¹⁴]
T_bg (K)	2.73	2.73	2.73
FWHM (km s⁻¹)	0.5	0.5	0.5

Notes. If a range is provided for a parameter, the MCMC algorithm explores the range starting with the initial value in front of the range. If a single value is indicated, the parameter is fixed to this value.
