RAR of our intermediate-z sample, with a_bar and a_tot derived from the model RCs corresponding to each galaxy’s best-fitting ΛCDM halo profile. The coloured points indicate the halo profile used in the disk–halo decomposition. The cross in the lower right corner indicates the mean 1σ uncertainties on the data points. The dotted black line shows the 1:1 relation. The purple curve represents the best-fit RAR, with $a_0{|}_{z\sim 1}=2.{61}_{-0.09}^{+0.13}\times {10}^{-10}\mathrm{m}/{\mathrm{s}}^2$ (i.e. as in Fig. 1).
