140 Mpc range, 4.8dB squeezing

The first attachment shows the DARM with/without squeezing today (blue: with squeezing, orange: without squeezing). The range is ~140 Mpc with squeezing and ~124 Mpc without squeezing. 

Above 1 kHz, DARM with squeezing is as good as the start of O4b and we have 4.8 dB squeezing at 2 kHz. The DARM below 1 kHz is worse and we will need to optimize FF and fix the calibration. We may also need to optimize PSAMS to improve the bucket sensitivity.

I ran SCAN_ALIGNMENT_FDS three times and accepted SDF as shown in the second attachment.
