Differences (Δ= Global-Local) between best-fit results for the parameters obtained with global and local DECam griz photometry for the DES galaxies, as a function of z. The left-hand side shows the results for τ_V and the right-hand side the ones for n. Results for the different galaxies are shown in gray. Binned means for each parameter are shown in orange, with error bars given by the standard deviation in each bin.
