Figure 5: The PN surface density at increasing distances from M 31 in strips parallel to its major axis, and outside 1.5 tidal radii from the centre of NGC 205 (see text). The zero point of the x-axis corresponds to the inner limit of our observed field. The dashed lines indicate the range of distances within which NGC 205 is located. |
