Background-subtracted Hess diagrams of seven regions along the Palomar 5 stream. The spatial interval in the standard coordinate ξ is marked over each panel. The red lines (a portion of the CMD selection box shown previously in Figure 5) encompass the main-sequence turnoff region of the cluster, as is very clear in the fifth panel. However, this population is also present in all of the stream regions, albeit at slightly fainter magnitudes at positive ξ, and slightly brighter magnitudes at negative ξ.
