Comparison of residual maps. Here we compare the modeled and residual maps (V_los, mdl and V_res) of different initial parameters (shown in Fig. 10) that we obtained by using Eq. (8). Upper row: the tilted rings using (Heald et al. 2016) model outputs that are based on their KAT7 observations and using rotcurv. For visualisation reasons, we interpolated the gaps using the scipy function 2d interpolation. For further analysis we focus on the tilted-ring frame. Lower row: the tilted rings using (Di Teodoro & Peek 2021) model outputs that are based on LVHIS observations and using BBarolo. The field of view is restricted to their V_rot parameters. Therefore the southern and northern arm are not evident in the residual map.
