Table 4 Drift correction results for tilt. The table shows values for the error in the accumulated tilt of the reconstructed sequences for the various reconstruction methods. Values are in degrees. Percentage values are not useful in this case, as the correct tilt angles are very close to zero for the beef data sets. For the nonmonotonic data sets, results are shown separately for the forward and reverse sweeps, as indicated by the f and r subscripts respectively.
