Demonstration of the correlation between some of the survey properties. In each panel, the mean and scatter values of the survey property indicated in the label of the y-axis are shown in bins of the survey property indicated in the label of the x-axis. The anti-correlation between the residual background counts in the coadds and the stellar number density is evident (left). There is an anti-correlation between the limiting magnitude in the r-band and the PSF FWHM r-band (middle). Furthermore, there is a correlation between the NIR magnitude limits in the H and the K_s bands (right).
