Table 3:

Infall properties for Clump 14 and 16, i.e. the two main infall regions.
	R^a	M^b	$\langle n_{\rm H_2}\rangle$ ^c	$v_{\rm in}$ ^d	dM/dt^e
	[pc]	[ $M_\odot$ ]	10⁵ [cm^-3]	[km s^-1]	[ $M_\odot$ yr^-1]
Clump 14	0.52	4900	1.26	0.6	$5.8\times 10^{-3}$
Clump 16	0.615	3346	0.52	0.5	$2.8\times 10^{-3}$

Notes. ^(a) Equivalent radius of infall region. ^(b) Mass from mm-continuum (see Table 2). ^(c) Average H₂ density, derived from the mass given in Col. 2. ^(d) Infall speed, determined from Simline modelling (Sect. 5.3). ^(e) Mass infall rate $\dot {M} \approx M/t = M~ v_{\rm in}/R$ .
