Table 3
Precession periods and depletion timescales of the models studied together with the maximum degree of asymmetry, the maximal shift in velocity space, the average dip, and the average HWB of the lines.
| # | τp (d) | τ0 (yr) | ξ | vshift | Dip | HWB |
|---|---|---|---|---|---|---|
| B1 | 27.2 | 4.3 | 0.13 | 46 | 0.47 | 874 |

| B5 (a) | 126.7 | > 1.2 | 0.13 | 37 | 0.48 | 852 |

Notes. Both vshift and the HWB are given in units of km s−1. All line parameters are measured when the disc mass is still significant, that is Mdisc ≥ 10−3 Ma. (a) Discs with τ0 > 1.2 are growing in mass throughout the length of the simulations. Determining a depletion timescale would require longer run times. (b) Circularisation happens before the gas can evolve into a disc.
