  1. IUL Vetoes Nelson Christensen Russ Bainer Carleton College LIGO-G020082-00-Z

  2. Strategy • Have list of inspiral “events” from Duncan and findchirp (LHO 2 km) • Trying to find a tool that finds simultaneous events in PEM or other interferometer channels LIGO-G020082-00-Z

  3. Varying Correlations • Tried CorrMon (Adrian Ottewill) • Measure correlation between AS_Q and another channel • 8 s intervals, looking for abnormal increases • RESULT: Difficult and not successful in seeing events simultaneous with findchirp “inspiral events” LIGO-G020082-00-Z

  4. NonMon – A correlated glitch tool • Jacob Fenton (Reed College undergraduate) • Program characterizes noise level –300 s • Specify magnitude of glitch (2s, 3s, etc) and how many times per second this threshold is exceeded LIGO-G020082-00-Z

  5. Configuration File LIGO-G020082-00-Z

  6. Output LIGO-G020082-00-Z

  7. Where can one also see Inspiral “Events”? Sometimes see it in seismometers LSC-POB_Q LSC-MICH_CTRL ASC-QPDX(Y)_(P, Y, DC) LIGO-G020082-00-Z

  8. Sample “Events” findchirp event at 694421111 LIGO-G020082-00-Z

  11. Consistent with Julien Sylvestre’s Observation • Julien found H2:LSC-MICH_CTRL could be used to predict glitches in H2:LSC-AS_Q • PSL signal FSS_RCTRANSPD_F noise correlated with L1:LSC-AS_Q glitches. Have not seen in H2 LIGO-G020082-00-Z

  21. NonMon Results: H2:LSC-AS_Q and H2:LSC-POB_Q • 8 s and 0.001 *16384 = 16 points per sec; 77 coincidences in 3600 sec, individual 257 events for AS_Q and for 292 POB_Q • 4.5 s and 0.001 *16384 = 16 points per sec; 343 coincidences in 3600 sec, individual 602 events for AS_Q and for 807 POB_Q LIGO-G020082-00-Z

  22. NonMon sees the Inspiral “Events”. Lots and lots of coincidences with POB_Q and MICH_CTRL H2:LSC-AS_Q with LSC-POB_Q LSC-MICH_CTRL ASC-QPDX(Y)_(P, Y, DC) Only sometimes does it register with seismometers LIGO-G020082-00-Z
