S.Klimenko, LSC, August 2004, G040393-00-Z BurstMon S.Klimenko, A.Sazonov University of Florida l motivation & documentation l description & results l noise stationarity for S2&S3 l summary & plans

S.Klimenko, LSC, August 2004, G040393-00-Z motivation l display performance of LIGO detectors to identify (new) problems during data taking runs (maintain high data_for_analysis/data_on_tape ratio) l give a reference point for burst searches in terms of sensitivity and rate l express detector performance in few burst FOMs detector sensitivity: range or strain (preferably for astro-motivated burst sources) noise non-stationarity & non-Gaussianity l latency Short (few minutes) to be useful in control room

S.Klimenko, LSC, August 2004, G040393-00-Z BurstMon l DMT monitor: Measures hrss amplitude of injections at 50% of detection efficiency and produce burst FOMs. l Method: The BurstMon performs real time injection of simulated bursts and detect them using burst analysis in wavelet domain. l Input: single detector AS_Q channel & injection waveforms l Output: dmtviewer & trends (min, sec) detector sensitivity, hrss @ 50% noise variability (non-stationarity) rates (complimentary to glitchMon) l reference: http://www.phys.ufl.edu/LIGO/burstmon/http://www.phys.ufl.edu/LIGO/burstmon/ l LIGO Note: BurstMon, T040162-00-Z

S.Klimenko, LSC, August 2004, G040393-00-Z Conclusion & Plans l BurstMon is a single interferometer burst detection engine implemented as a DMT monitor. l It has real-time simulation pipeline for estimation of the detection efficiency for injected waveforms. l Several FOMs are produced: hrss @ 50% detection efficiency (for each type of waveforms) noise variability, rates,... suggestions are welcome l Plans finalize implementation issues include real-time calibration as soon as available some minor optimization (almost in real time) commissioning - run on regular basis get ready for the next engineering run
