Figure 1: As a consequence of moving the Beam Splitter from Drift Control (V1:SAT_BS_AATX = 1) to Full Bandwidth (V1:SAT_BS_AATX = 2), between 8 AM and 5 PM of May 23 there seems to be a reduction in the amount of glitches clustered around 150 Hz: refer to Figure 2 and Figure 3 with the Omicron glitchgram of V1:LSC_DARM and V1:Hrec_hoft_16384Hz.

In Figure 4 and Figure 5 the Amplitude Spectral Densities of V1:LSC_DARM and V1:Hrec_hoft_16384Hz are plotted at two different times (blue: Full Bandwidth, purple: Drift Control) around the 150 Hz line and at low frequency. A noise reduction is visible in Full Bandwidth in the band around 150 Hz, together with the growth of a small bump at 158 Hz (most noticeable in LSC_DARM). At lower frequency, and as expected, a small increase in the LSC_DARM noise is visible with the BS in Full Bandwidth.
