RAR of our intermediate-z sample, where a_bar and a_tot are derived from the RCs modelled in the MOND framework. 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 $a_0{|}_{z\sim 1}=2.{19}_{-0.10}^{+0.12}\times {10}^{-10}\mathrm{m}/{\mathrm{s}}^2$ (i.e. as in Fig. 1). The cyan curve shows the relation, as inferred using the median a₀ value from the MOND fits to the individual data cubes, namely a₀|_z ∼ 1 = 2.27 × 10⁻¹⁰ m/s².
