Notes. The systemic velocities shown in the first column are estimated from the Keplerian modelling of the circumprimary disc velocity maps (see Sect. 4.1 and Table 5 for further details).(*) Sign of partial absorption in the redshifted velocities.(†) Redshifted velocities totally absorbed.(‡) Sign of partial absorption around the systemic velocity.
