| filter | To find an optimal value of CoR automatically. | High | - Since the computational cost of this auto-centring process is high, it is normally applied to a small but representative subset of data (this can most conveniently be done with the aid of the preview parameter of this process).
- Any reconstructor process included in a process chain after VoCentering will have its centre_of_rotation parameter automatically set to the value determined by the auto-centring process.
- VoCentering should normally be included after a ring-artefact suppression process (such as, e.g. RemoveAllRings), but before any low-pass process such as PaganinFilter or FresnelFilter.
