Image Details
Caption: Figure 10.
Colors of annuli from the stacked images. Each radius is the midpoint of the annulus. The colors are corrected for the average foreground Milky Way reddening of the seven stacked galaxies (E(B − V)f = 0.02). The uncertainties are from a “jackknife” process described in the text.
