update on the locking activity |

We tried to measure the sensing matrix for MICH and PRCL last night. They look too much mixed as we expect... the matrix may be posted later. We suspect the IX and IY of the MICH excitation is not balanced very well, although Kiwamu adjusted that about two weeks ago, and it is mixing the dof. We'll try to balance it again, ans see the matrix.

Some updates on the locking activity:
- Started summarizing the data of the Michelson lock in a wiki page:
- Gradually moving on to the PRMI lock
- The lock stays for reasonably a long time (~20 min or more)
- POP22/110 demod signals seemed just ADC noise.
- A first noise budget is in process
- The glitches make the noise level worse above 40 Hz or so in both the MICH and PRCL budgets.
- Sensing matrix will be measured tomorrow
- The data will be also summarized in a wiki page
