Table 1.

Tilt geometries and percentage of missing data. (a) The percentage of missing data for different tilt geometries and tilt angles. (b) The tilt angles for different tilt geometries and the percentage of missing data. * For conical/random conical (RC) the angular value represents the fixed tilt angle.
