Extended Data Fig. 5: Impact of the choice of velocity baseline.

The figure shows how the choice of vϕ,mod affects the residuals from vϕ, as in the second row of Extended Data Fig. 2. The top panel shows the different underlying models compared to the unprojected data, while the bottom panel shows the residual between the model and the observations. Regardless of the vϕ,mod chosen, the structure in δvϕ = (vϕ − vϕ,mod)/vϕ persists.
