Radial UV color profiles for six different galaxies. The blue profiles correspond to the color profiles using the background estimate from the standard GALEX pipeline (here called GALPIP). The color profile resulting from our background estimate (UV LSB) is shown in red. When the effect of the PSF is taken into account (green profiles), the shape of the color profiles changes dramatically in the outermost region beyond the galaxy edge. The edge position is marked as a vertical dashed line.
