Comparison of different galaxy-removal schemes applied to deep CFHT images. The first column shows the original image. The second shows the residual image after subtraction of a PCA reconstruction of the galaxy. The third and fourth columns show the subtraction of a single and double elliptical Sérsic profile respectively, using GALFIT3 . The PCA-subtracted images are rotated by construction of the PCA basis, but the GALFIT -subtracted images are not, in order to avoid interpolation when not mandatory.
