Parameter	QC	HVC	LVC^a

R_int (pc)^b	55−73	65−80	65−80
T_dust (K)	95−120	90−105	~90
τ ₁₀₀	1−3	1.5−2.0	≲1
R_out/R_int	−	≲1.5	~1.5−2
v_int (km s^-1)	−	1700	~300
v_out (km s^-1)	−	100	~200
N_OH (10¹⁷ cm^-2)	5−16^c	1.5−3	~0.3
p_f/R_out^d	1	~0.8	~1

Notes. Parameters for the LEC (low-excitation component) are not well constrained (see Sect. 3.4) and are omitted.

^(a)

Uncertain parameters from the present data.

^(b)

For f = 1.

^(c)

Column density per unit of τ₅₀ (G-A12).

^(d)

p_f/R_out = 1 is a fully spherical model, while p_f/R_out < 1 simulates collimation in the direction of the observer.
