20. The rise height before ambient relaxation represents a limit where even the residual vibrational spikes on the optical table cannot relax the CL compared to its constant movement due to the forced, slow (7 μm/s) plate motion used to prepare the CL in the advance or recede conditions. Thus, this rise height approaches a "zero-vibration" limit.
