Observational parameters for the CH₃OH v_t = 1 lines, and results of the LTE modelling for CH₃OH.






Observed parameters			LTE fit parameters
		Δv	N	size	T_ex
	(km s⁻¹)	(km s⁻¹)	(cm⁻²)	(′′)	(K)

A	− 48.1 ± 0.1 (− 4.6)	4.5 ± 0.2	1.6 × 10¹⁹	0.4	160
B	− 39.9 ± 0.1 (+ 3.6)	5.6 ± 0.1	2 × 10¹⁹	0.4	170

Notes. ^(a)The number given in parentheses corresponds to the difference between the line velocity and the − 43.5 km s⁻¹ v_lsr of the source.
