	We tried to record sum signal at several powers without success. For some reason the X and Y amplitudes were really disturbed (jumpy), so as the sum. On low power around .20W they were constant, but as soon as we got above .70W they were really disturbed. And also, every time we increased the power we had to adjust the x and y amplitudes. The pictures in the corresponding link show that:		We tried to record sum signal at several powers without success.
