Figure 5
Fourier ring correlation (FRC) curves for two images reconstructed from separate instances of Poisson-noise-included simulated data sets, for (a) NFH, (b) FFP and (c) NFP. Only results obtained using the LSQ cost function of equation (7[link]) are shown. Each curve is labeled with the fluence nph in quanta per pixel. Also shown on the plot is the 1/2-bit threshold curve that is commonly used to define the achieved spatial resolution based on the spatial frequency of the crossing with the experimental FRC curve (van Heel & Schatz, 2005BB24), as indicated by red circles for a fluence of 8 in (a) and (b). These FRC crossing normalized spatial frequencies are used in Fig. 6[link].
