In order to check the behavior of the new camera signals I ve scanned the beam on the NE vertical direction of about 2mm (with a speed of 1mm/h), figure 1.

the camera signals are well detecting the beam displacement, see figures 2 and 3.

the calibrations are:

NEY_cam = 7.626*NEY_dither -177.8;

NEY_beam = 10.29*NEY_dither+1089;

the overlap of the 3 signals (after being calibrated) is shown in Figure 4.

From this test these signals have been confirmed to be usable and more performing in terms of noise, as it was evaluated in the previous analysis,  than the dither signals.
