General issue

• Interferometer status
  • Detection range is about 40kpc at maximum
  • There is still some peaks in the lower frequency
    • Type-A resonant frequency etc...
  • Mostly AS PD noise at higher frequency
    • PRFPMI trial at end of this year
  • Peaks appeared at higher frequency
    • PEM injection to REFL table
  • December 17-24 24h engineering run

    • wiki
