Properties of the mock sample compared to the kinematic sample. From top left to bottom right, we show the cumulative distribution functions (CDFs) of redshift, magnification, stellar mass, SFR, effective radius, apparent size-to-PSF ratio, S/N in the brightest spaxel, effective S/N, circular velocity at 1.8R_e and velocity dispersion floor. The rotation-dominated (v_1.8/σ₀ > 1) subset of the kinematic sample with well-constrained velocities (Δv_1.8/v_1.8 < 30%) is shown in solid orange. A further restriction to μ < 6, applied to match the magnification range of the mock sample for a fair comparison of the magnification CDFs, is indicated by the dash-dotted orange line. The parent mock sample appears as a dashed blue line, while the mock subsample satisfying selection criteria similar to the kinematic sample (S/N_eff > 10, $\sqrt{\mu }{R}_e/R_{\mathrm{PSF}}>1/2$ and v_1.8/σ₀ > 1) is shown in solid blue.
