During the ER, BNS range was changed for each lock segemnts (e.g. https://gwdet.icrr.u-tokyo.ac.jp/~controls/summary/day/20191223/plots/K1-LOCKED_LSC_13F4B6_TIMESERIES-1261094418-86400.png)
I compaire the DARM displacement for each segments, duration > 1 hour.
This is the list of such segments :

| 1260604820 | 17569 | 8.5 |
| 1260622963 | 26998 | 6.8 |
| 1260650400 | 11489 | 6.4 |

| 1261119565 | 5461 | 7.9 |
| 1261125486 | 28536 | 6.4 |
| 1261172127 | 8690 | 5.7 (worst) |
Here, I compaire the best and worst case.
the floor level is about factor 1.5
significant pleaks/bumps are 24-28Hz, 84Hz, 99-103Hz, 120Hz
the first 8 segments :
although some peaks & bumps are changing, the floor level looks more essential for the BNS range
