Simulation results when the PSF values of FWHM and β are known and held constant. Top row, first panel: delta Flux of [O III] against fitted A/rN value of each source. Top row, second panel: delta M₅₀₀₇ against source A/rN. Top row, third panel: delta radial velocity as measured from the offset of the [O III] emission line. The red points are the median value binned by A/rN. The upper and lower parts of the red region indicate the 86th and 16th percentile, respectively.
