Comparison of the predictions of the model with rλ − c = −0.4 and s = 0.4 (red lines) against the observations from the SPARC catalogue (grey circles). We adopt two different velocity definitions for the TF relation: V2.2, the circular velocity at 2.2Rd, and Vflat, which we compare with Vc(5Rd) where our model rotation curves are approximately flat. The light red band shows the 1σ intrinsic scatter of the model.
