This page provides a brief overview of currently running or soon-to-be-running DMT monitors. Each monitor provides (or is supposed to provide) more detailed documentation, accessible from the "spi page" that monitors the monitors running on the Hanford and Livingston DMT workstations.

At the bottom of this page are additional links related to the DMT figures of merit and  infrastructure.

• BicoMon (S. Penn) - Displays and records bicoherence quantities for requested channels & bands.
  
  
• Blrms (E. Daw) - Displays and records band-limited RMS (New_Seis_Blrms looks only at seismic channels; LXO_ifo_blrms looks at AS_Q) -- Obsolete?


• HistCompr (J. Zweizig) - Histograms filtered data - visible in DMT Viewer (program called IFO_Hist).


• LineMonitor (S. Klimenko) - Tracks specified lines in several IFO channels, also reports detected lines above threshold SNR. Several different versions typically running, looking at different channels.


• MultiVolt (D. Sigg) - Monitors line voltage amplitude/phase, including harmonics.


• NoiseFloorMon (R. Grosso / S. Mukherjee) - Monitors median-based band-limited noise floors, variances, and large excursions.


• PSLMon / RMSBands / DataQual (J. Zweizig) - PSLMon is comprehensive suite of tools. RMSBands and DataQual are programs that record band-limited RMS in selected channels.

• PulsarMon (G. Santostasi) - New monitor that produces figures of merit for the pulsar search, including sensitivity to ellipticities of known and possible rotating neutron stars and time required at present sensitivity to reach spin-down limits on known pulsars.
  


• SenseMonitor (P. Sutton) - Estimates seeing range to binary inspiral of NS-NS system (1.4 solar masses each). Uses strength of 1kHz calibration line to rescale the open-loop gain and sensing function for accurate tracking of the interferometer calibration.

• StochMon (M. Cenac / B. O'Reilly / J. Whelan) - New Monitor that produces figures of merit for the stochastic search, mainly the sensitivity to gravitationa.

• Absglitch (R. Rahkola/M. Ito) - Soon-to-be-discontinued version of GlitchMon, allowing for absolute (not strictly adaptive) thresholds.

• BurstMon (S. Klimenko / A. Sazonov) - BurstMon is a new monitor that produces several figures of merit relevant to the burst search: h_rss value at 50% efficiency (strain/sqrt(Hz));  non-stationarity measures; and glitch rates./characteristics.
  


• DewarMon (E. Harstad) - Detects seismic glitches from sudden creaks of liquid nitrogen dewars.


• EqMon (R. Rahkola) - Earthquake monitor with dedicated audible alarm (not enabled as of mid-December 2002). 


• GlitchMon (M. Ito) - Looks for sudden glitches in hundreds of channels (now allows for both adaptive and absolute thresholds). Several different versions running typically, looking at different sets of channels.


• InspiralMon (D. Brown) - Displays inspiral search analysis triggers found by quasi-online ONASYS programs running on local observatory clusters.


• LockLoss (D. Chin) - Displays and records all lock transitions, displays IFO state vector in abbreviated form.


• PlaneMon (E. Goetz) - detects low-flying propeller aircraft from microphone data and reports back estimate aircraft speeds, rest-frame fundamental frequency, and distance of closest approach to each microphone channel. Spectograms for candidates are archived.


• PSLMon / ZGlitch / DataQual (J. Zweizig) - PSLMon is comprehensive suite of tools. ZGlitch and DataQual are programs based on PSLMon that record trigger rates on filtered data channels for exceeding N sigma. Threshold based on running, weighted mean and standard deviation.


• PTMon (N. Zotov) - Looks for transients, using a robust algorithm borrowed from the UGSG.


• SegGener (J. Zweizig) - Generates "segments" for the meta-database of "good data" based on the IFO state vector.


• ShapeMon (S. Marka) - Looks for channel-hopping via sudden gross spectral changes (seismic channels for now - may be generalized in future). Has interface to EPICS with MEDM display on main "site map".
  
  
• Station (J. Zweizig) - Measures non-stationarity (short-term variations in noise floor) and provides a spectrum of the variations.


• SuspensionMon (B. Stubbs / R. Rahkola) - Looks for out-of-bounds behavior in suspensions channels (recall the uncontrolled side motion seen in H1 during S1, leading to "heartbeat").


• WaveMon (S. Klimenko) - Looks for correlated glitches between pairs of data channels, using a robust percentile-based algorithm for identifying statistically significant correlations.
