Result of the galaxy removal on four of our simulated Einstein rings. The left panel displays the four original images. From left to right, the other panels display galaxy removals when 10, 50, and 200 PCA coefficients are used. The reduced χ2 are q = 1.74, q = 1.00 (i.e. optimal number of coefficients), and q = 0.9 respectively.
