Here's some plots showing the kind of performance we have in the corner station. Nothing new here, just wanted to do a quick status update.
For the 3 chambers, we can make some general comments:
- we're reinjecteing some noise below 100mHz in X and Y
- we're hitting the noise floor pretty quickly in the rotational degrees of freedom.
- some isolation is provided by stage2, but it's not very aggressive (lot of room between 1 and 10Hz). The good thing with this configuration is that we're not introducing some extra noise at low frequency (this comment is true for ITMX and ITMY. BS is on damping only for ST2).
