Table A.1

Gaussian fit results to the OH line components using the velocity range [− 100, 30] and first order baselines.

Component	^∫T_mbd3	T_peak	Δ3	3−3_lsr
	[K km s^-1]	[K]	[km s^-1]	[km s^-1]

Envelope 1 + → 1 −	3.9 ± 0.4	0.8	4.5^a	11.9 ± 0.2
Envelope 2 + → 1 −	11.7 ± 0.6	2.4	4.5^a	0.8 ± 0.1
Envelope 1 + → 0 −	5.7 ± 0.5	1.2	4.5^a	–3.3 ± 0.2
Outflow (blended)	36.7 ± 1.3	1.3	27.4 ± 1.0	4.1 ± 0.4

Notes. The 3−3_lsr velocity scale is given relative to the laboratory frequency of the 2 + → 1 − component (3_lsr = −38.4 km s^-1 = 1837.817 GHz).
