Figure 7
Exposure time requirement for a given resolution, deduced from the width of the TF for the HIO algorithm with output averaged using phase adjustment in reciprocal space (solid squares) and cross-correlation in real space (open circles). The solid line is the least-squares linear fit to the former data set for resolution higher than 30 Å. Other lines are given for comparison with simple analytical predictions from Howells et al. (2005 ) (dashed line), Shen et al. (2004 ) (dotted line) and this paper (dash-dotted line) with parameter P = 5. |
