Summary of the simulation parameters (the star labels of our fiducial model).

Model μ AD Ω0 (Hz) t0 (kyr)
HYDRO No 9.5 × 10−15 28.0
MU5I 5 No 9.5 × 10−15 27.9
MU2AD 2 Yes 9.5 × 10−15 28.2
MU5AD 5 Yes 9.5 × 10−15 27.9
MU5ADf 5 Yes 2.1 × 10−14 28.4

Notes. μ is the magnetisation parameter, AD means ambipolar diffusion, Ω0 is the initial rotation frequency, and t0 is the time of the formation of the first sink particle.
