Notes. Name is given by the name from the literature (when available) or the shortened name from Apertif. Inclination is denoted as i and the H I morphological position angle as PA_H I. Geom. gives the set of geometric parameters used for kinematic modeling (either H I or optical). PA_kin is the kinematic position angle, ΔR the separation of the rings used for kinematic modeling, N_rings is the number of the rings in the kinematic model, R_out the outermost radius of the model (number of rings times ΔR), and beam/ΔR the oversampling rate of the rotation curve along the kinematic major axis. Finally, σ_V is the mean velocity dispersion in all rings and V_rot, V_A, and V_circ are the maximum rotational velocity, the asymmetric drift, and the circular velocity, respectively. Upper errors on rotational and circular velocities are unconstrained and therefore not reported for galaxies whose inclinations are compatible down to inclinations of 0°.

^( * )Rotation velocity is likely tracing the flat part of the rotation curve, as seen from the shape of the PV slice along the major axis.

^( † )Galaxy was flagged as having unreliable rotational velocity (see Sect. 3.2.3).
