Example bulge-to-disk decomposition of an H = 22.2 galaxy from the GOODS-South field, which is among the faintest galaxy in our sample. The first column shows the observed HST WFC3 image of the galaxy, and we also provide its main physical properties in the top left corner. The second column shows the best-fit disk (top) and bulge (bottom) components as extracted by GIM2D. The third column shows the residual of the image after subtracting the bulge (top) and disk (bottom) to visualize the profile of the other component. Finally, the fourth column shows the residual image after both components are subtracted. The best-fit parameters are given in the top right corner.
