These plots are for all processed coadds that have magnitude thresholds for unconfused areas, which are 15.50, 14.75 and 14.25 mag for J, H and K, respectively. The first group of plots show all the background sigma points, and the scale of the coadd noise plots are set equal to that of the background sigma plots. The second group of plots shows the full range of coadd noise values.
