The baryonic TF (bTF) relation versus the maximum velocity (top panel) and versus the v + σ (or S_0.5) index (bottom panel). We overplot the best-fit relation of rotating galaxies (blue symbols) using the local slopes by McGaugh (2005) (plotted as solid black line in the top panel, McG05) and by Kassin et al. (2007) at z ~ 1 (plotted as solid black line in the bottom panel, K07). The other fit in the top panel is by Puech et al. (2010) (P10, z ~ 0.6, solid, orange line) and in the bottom panel by Gnerucci et al. (2011) (z ~ 3, long-dashed-dotted magenta line, G11). The cyan shaded area shows the 1σ error on the zero-point parameter (the intrinsic and total scatter is plotted as cyan dotted line and cyan dashed line, respectively). Symbols are as in Fig. 1.
