Caption: Figure 3.

Same as Figure 2, but for NGC 5897. A clear photometric overdensity is seen extending from the GC beyond rJ (yellow circle). A dashed blue circle is overplotted at r =  28’ to guide the eye, roughly at the radius out to which the photometric excess exists. Note that the excess does not preferentially align with the proper motion of NGC 5897 (red arrow); this is expected given the recent pericenter passage of NGC 5897 (see Section 3.1 for more details).
