Figure 2
Plots of radial-averaged cosine phase error versus resolution for different dose rates. (a) Radial-averaged FOMs are given for a medium-flux series on Hb in a low-salt sample for integrated flux densities of 50, 100, 150, 200 and 250 e Å−2. (b) Close-up of (a) showing the first and second zero crossing of the CTF for a defocus of −3.37 µm. Radial-averaged FOMs for (c) the low-flux and (d) high-flux short-exposure series. |
