Density profile parameters from fitting the N(H₂) map derived from 8 μm extinction.

Source	n_c	r_flat	R^(a)	Mass^(b)
	(10⁵ cm⁻³)	(au)	(pc)	(M_⊙)
L694-2	8.3(0.2)	2700(50)	0.1	4.0
L429	9.5(0.5)	4000(400)	0.1	8.3
L1517B	3.2(0.1)	3200(100)	0.1	2.0

Notes. ^(a) The maximum outer radius R in the fits is set to 0.10 pc for all three cores. ^(b) The total mass is calculated within a common radius of 0.05 pc. Uncertainties of parameter n_c and r_flat are listed in parentheses as absolute values.
