Figure 3.

X-ray diffraction image of squid HMM crystal. The five resolution rings in the right image are at 21.54, 10.79, 7.22, 5.45 and 4.39 Å; the latter two pass through the boxed region, which is magnified in the left image. Note that the diffraction is anisotropic, i.e. diffraction is observed past 4.4 Å resolution in some directions but to only ∼7 Å resolution in other directions, and a second minor lattice is seen at low resolution. (These factors may account in part for the relatively high R _merge given in Table 1 ▶.)
