Viscous timescales in the different models and the precession period of the discs.

#	α	t_ν (year)	τ_p (day)
B1	0.01	2.4756	27.2
B2 ^(a)	0.001	24.755	−
B3	0.05	0.4951	10.6

Notes. The parameters that differ in each model have also been indicated. ^(a) Precession period cannot be determined because a disc structure has not yet developed within the simulation time.
