Contour levels used for the Apphot analyses of the Galaxy Total (top, 2a), Nucleated Bulge (middle, 2b), and Visible Tidal Stream (bottom, 2c) as described in Table 4. All contours were based on a sky-subtracted version of the archival 3.6 μm SST image. For each analysis, the outermost contour (drawn in red) was taken as the sky value, thus Apphot considered all light within each exhibited contour in the photometric analysis. The physical dimensions of the topmost image (2a) are 44.7 kpc × 30.4 kpc.
