Top: relative variation of spot width as a function of spot peak flux on CCD E2V-250 at two wavelengths, 550 nm (left panel) and 900 nm (right panel). Bottom left: MegaCam difference of second moments of stars to the average as a function of peak flux. Bottom right: same measurement on DECam CCD (S11). A small color correction is applied in both cases. One notes that in all cases the size increases linearly with the peak flux.
