 Some updates on the locking activity:

• Started summarizing the data of the Michelson lock in a wiki page:
  • https://wiki-40m.ligo.caltech.edu/Interferometer_Characterization/Michelson_Noise_Budget
  • Some careful analysis of the OSA signals are missing
    • Besides the analysis we need to work on the mode matching to get a better resolution as Mirko achieved.
• 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
