Comparison between True and measured properties of 400 mock galaxies. Top row panels: Comparison between the input structural parameters of the mock galaxies, and the values measured by the photometric pipeline. The parameters compared are: apparent magnitude (mr), effective radius (Re), position angle (Θ), axis ratio (b/a), and Sérsic index (n). The red solid lines represent the 1:1 ideal ratio. Mid and bottom row panels: The blue lines are the running means of the differences between the input and output parameters, as a function of their input and output , respectively. The differences are calculated as input – output. The red dotted lines in the bottom row panels show the fits to the standard deviations of residuals, as defined in Eq. (A.2).
