Measured RAR of the KiDS-bright isolated lens sample (black points with 1σ error bars) compared to two ΛCDM simulations: MICE and BAHAMAS. The accelerations where uncertainty in the photometric KiDS redshifts affects the KiDS-bright isolated lens selection is indicated by the light blue shaded region. The MICE results (red band) emulate the effect of the redshift uncertainty in KiDS, while the BAHAMAS results (orange band) reflect the median and 16th and 84th percentiles of the simulated lens galaxies. The MICE simulation, though limited to low accelerations by its resolution, succeeds in reproducing the lensing data. The result from the BAHAMAS simulation runs approximately parallel to the MICE curve, but underestimates our measurement by 0.5 dex due to the biased SHMR of the BAHAMAS isolated galaxies (see Sect. 5.3).
