Figure 2
Average power spectra, CTF curves and fit to the CTF curves. The logarithm of the power spectrum averaged over particles is shown for four micrographs, at nominal defocuses of δf = −1 (a), −2 (b), −3 (d) and −4 µm (c). Rotationally averaged profiles of these spectra (green line), the calculated CTF (red line) and the Gaussian baseline (blue line) are shown in (e), (f), (h) and (g), respectively. |
