H2 Optics Roll Mode Flags:
Channel and Frequency Bands
- H2:DARM_ERR 70-110Hz
- H0:LVEA_SEISZ 17.26-17.28Hz, 17.58-17.6Hz and 17.6-17.62Hz
- H2 FMX Roll Mode Freq = 17.589Hz
- H2 FMY Roll Mode Freq = 17.610Hz(Table of H2 Interferometer Resonances)
- H2 ITMX Roll Mode Freq = 17.267Hz
- H2 ITMY Roll Mode Freq = 17.270Hz
Flag time period during strong seismic noise at H2 optics roll mode frequency
- Aimed for flagging the compressor noise at LHO staging building
- Looked for large H0:LVEA_SEISZ signal at ~17.27Hz, ~17.59Hz and ~17.61Hz separately, then combined three sets of flags into one
- Dead Time Fraction: 0.877%
