PSF treatment applied to stars in the Subaru frame (upper panel) and in one of the frames of the CFHT mosaic (lower panel). Semi-major axis distribution in the CCD, of the sources classified as stars, before (left) and after (right) the PSF deconvolution. For a better visualization of the plot, semi-major axes have a different scale than the CCD axes. Semi-major axis scale is given by the red thicker segment in the upper left-hand corner and corresponds to 3 pixels. We highlight that the semi-major axis is more randomly distributed and is significantly smaller after taking into account the PSF.
