S2 / S3 Investigation Report:

• Data quality investigations: (S2, S3 )  & segment repository (S2, S3) - (John Zweizig, Keith Riles)
  John reported he is working on indentifying airplanes at LLO during S2 (S2 LHO and S3 LHO/LLO already done). Gaby mentioned that after the final S3 calibration release is ready (version 3), there will be a new set of associated data quality flags indicating problematic calibration intervals. These new flags should supersede the old flags. KR briefly summarized the recent release of S3 data quality segments.

DMT Software:

• Critical DMT issues for M5 preparation:
  
  
• John Zweizig: Infrastructure status and deadlines for new monitors
  Because the new EasyCalibrate class makes frequency domain analysis more useful, in general, John has been cleaning up the FSeries infrastructure, including adopting the FFTW library. One issue is that the old DMT DFT normalization has differed from the official LSC spec. John will conform to the spec and send out a note to DMT authors warning of the change.
  DEADLINE for new code to be run in M5: Friday October 15
  John Whelan mentioned very recent problems running online on fortress. JohnZ suspects a recent reboot and will look into the problem. He is concerned about frame losses approaching 20% at LLO in recent days. Preliminary investigations haven't revealed the source. He has contacted Chethan Parameswariah for help. 
  Sergey requested that JohnZ create workspaces or provide sample makefiles so that monitor authors can more easily work on only their monitors directly in the CVS tree without having to rebuild all other monitors after a CVS update. JohnW and Keith agreed that it would be nice to provide a sample makefile for stand-alone monitor building. JohnZ agreed to look at breaking out a subset of the current global makefile. 
  
  
• Patrick Sutton: Calibration infrastructure
  The new EasyCalibrate class is now available for general use. SenseMonitor itself has been updated to use the new class and should serve as a useful template for other authors wanting to use EasyCalibrate. Documentation is available in html. JohnZ mentioned that in addition to being available as source code in the CVS tree, the new code is in compiled form on the Caltech DMT machines. The new class works only for H1, using the old S3 calibration reference functions. The calibration team will need to run a root script to generate new EasyCalibrate xml files, presumably before E11.
  
  
• John Whelan / Mark Cenac / Brian O'Reilly: StochMon
  StochMon compiles and runs sucessfully on frame file and will be put into CVS by the end of the weekend. For the M5 mini-run, it will work for H1-H2 and H2-H1 (true ifo against reference ifo).  They are hoping to incorporate an overlap reduction function into the monitor before M5. KR suggested focussing instead on incorporating EasyCalibrate as the higher priority.
  
  
• Ken Ganezer: seis_blrms
  Ken has a new version of seis_blrms compiled and running which he believes will correctly handle data dropouts. KR suggested running it at LLO where data dropouts are now rampant (see above).
  
  
• Sergey Klimenko: BurstMon
  Sergey has started incorporating EasyCalibrate into BurstMon and hopes to have a running version in a couple of days.
  
  
• Giovanni Santostasi: PulsarMon
  Giovanni reported by e-mail that he has implemented but not yet tested dmt viewer plots. He will try incorporating EasyCalibrate now that it is available.
  
  
• Rauha Rahkola: SuspensionMon
  Rauha will be putting the new SuspensionMon version (bug in trending fixed) into CVS this weekend.
  
  
• Other DMT reports:
 
• Lindy Blackburn: KleineWelle (report, home page)
Lindy reported on KleineWelle which is a DMT program developed primarily for offline burst search analysis, but which he plans to adapt to online control room use. The single-IFO glitch finding is based on pixel clustering in the time-frequency plane where the frequency basis functions are dyadic Haar wavelets (similar to BurstMon). Linear predictive filtering (order 1024) is used for conditioning. Lindy showed efficiency vs hrss plots for several Gaussian waveorms. He also showed glitch rates from S3 playground for H1, H2, and L1, along with times of triple-coincidence triggers. Rate variations of more than an order of magnitude are observed. KleineWelle has also been used to study glitches in auxiliary channels as veto candidates. Half of the 30 triple-coincidence AS_Q triggers can be vetoed from other channels, but deadtimes have not yet been determined. Lindy will be adding KleineWelle to the GDS CVS treee soon and will continue development of an online gltich rate monitor. JohnZ wondered if Sergey's wavelet library could be used by the monitor instead of its own library, so that the DMT supports only one set of generic wavelet routines. Lindy will take a look at Sergey's routines.
