Secondary Tilt and Decenter (II) dax = 170 nm rms day = 130 nm rms dlx = 310 nm rms dly = 120 nm rms da = 15.4 nm/mas dl = 43.1 nm/mas
Conclusions How are we going to measure the interaction matrix ? Is there an equivalent g’ for the pyramid sensor ? How are we going to setup the diagnostics both from WFC and technical camera ? Do we need to implement a feedforward correction of vibrations ?
