For the misalignment test of Oct 9 there was a recalibration done after fixing the issues in Hrec. The corresponding data are in /data/dev/hrec/hrectest/hrec_srhinj9-1380880808-3608.gwf
Figure 1 shows the recalibrated spectra during 1h of that test. An aligned SR configuration correspond to the last two curves when there is ~700mW on B1p. There was during that actually a clear improvement at 100Hz in sensitivity, and noise getting higher at 1kHz due to the lower bandwidth of SR+arm cavity pole.
Figure 2 is the same data zoomed around 100-145Hz showing that the calibration line at 106Hz is constant, and the 137Hz calibration lines moving by less than 5% in amplitude.
Figure 3 zooming vertically further in, the noise floor level changes by a factor 1.45, a bit less than during the Nov 1 test at 12W input power when it changed by a factor 1.65, for a factor 2 decrease in higher order modes (as a measure of the SR misalignment). But in general it is very similar.
Figure 4 are the corresponding spectra of B1, as for the 12W test the noise floor is not moving in level, and what is changing is the height of the calibration lines (the interferometer optical gain).
