... The OPD stability during the 40 K TV test at CSL was between 5 and 10 nm rms (see Figure 15). This is higher than the stability reached during the integration phase in the TNO laboratories (0.9 nm rms), due to the higher disturbance spectrum of the TV facility (~10x higher than in the TNO laboratory ...
