Parameters varied for the study presented in Sect. 4.

Label	Meaning	Values	Equation(s)	Section(s)
ξ	Temperature scaling factor	[1, 9]	(6), (9), (10), (16), (17), (18)	4.1
a₀	Dust monomer size	{0.1, 1}μm, a₁	(31)	4.2, 4.4
χ	Velocity fluctuation scaling factor	[1, 100]	(16), (17), (18)	4.3
ε₀	Initial and infall dust-to-gas ratio	[0.01, 0.07]	(15)	4.5
ε_mid,crit	Critical midplane dust-to-gas ratio	{0.5, 1}	−	4.5

Notes. Square brackets denote intervals, whereas curly braces denote a set of values. The value a₁ represents the size of the large grain population in the two-population model.
