Visual inspection score related to the Einstein radii and log₁₀(S/N) of the lensed source in I_E band. The colour maps represent the VI score, and the colour transition point from red to blue was set at 1.2 because this is the visual inspection score cut for candidates in category A. Red shaded areas therefore represent a region in which we can recover category A lens candidates, and blue shaded ares represent a region in which we struggle as visual inspectors to properly recognise or miss lens candidates.
