Plots of the R factors versus iteration number for the silver nitrate, aluminophosphate and dipeptide precursor reconstructions, left to right, respectively. The solid line traces the average R factor over eight independent reconstructions with the same parameters but different random starts. The shaded regions above and below the average indicate ±3 standard deviations from the mean of the eight runs. The R factor calculated at each step decreases, indicating that the reconstructed intensities are approaching the target intensities.
