Relation between the log₁₀(Blendedness) parameter and the photometric accuracy of synthetic stars (upper row, a and b) and galaxies (lower row, c and d). Left-hand columns (a and c) show the uncertainties in PSF and/or CModel magnitudes. Right-hand columns (b and d) show the uncertainties in (g − i) colors. Filled contours and open contours show results for goodSeeing and badSeeing tracts, respectively. log₁₀(Blendedness) = −1.0 is marked using a vertical dashed line. (Color online)
