*Summary of precisions and accuracies of forced PSF colors using (g − i) and (i − y) colors and in both goodSeeing (FWHM = 0|${^{\prime\prime}_{.}}$|45) and badSeeing (FWHM = 0|${^{\prime\prime}_{.}}$|70) tracts based on the standard deviation and mean value of the difference between output forced PSF color and input value (ΔColor) shown in figure 7. Here, we describe the precision and accuracy of PSF color measurements using the standard deviation and mean values of ΔColor in bins of input i-band magnitudes.
