DMT Software Status & Plans:

• Needs and planning for engineering runs and S4
  KR briefly reminded everyone of the tentative upcoming engineering run schedule, with a mini-run at LHO in mid-October and a weeklong run at LHO in mid-November. To get ready for the mini-run, we need new or improved DMT monitors to be up and running 24/7 in mid-September.
  
  
• Status of DMT infrastructure:


• John Zweizig: Version updates, etc
  John has been helping Patrick Sutton lay the groundwork for a new DMT calibration class (see below). He has written a generic XML parser that can be used to read the input files Patrick needs for carrying out calibrations. If that information can later be stored and retrieved from frames, the new class can be readily adapted. It includes handy utilities like "find".
  John is also improving the automated building of the DMT to cope with special cases, such as the absence of an FFTW3 library.
  
  
• Patrick Sutton: Calibration infrastructure
  Patrick provided a detailed set of calibration class templates to be used by DMT astrophysical figure-of-merit monitors. These new classes will include FDEasyCalibrate, which provides a user-friendly and standardized interface to obtain calibrated power spectra, where the mechanics of reading in reference functions and gain constants is hidden from the user. SenseMon itself will eventually use this infrastructure, which is based in part on the original core of that monitor. The input XML files will need eventually to be produced routinely by the calibration team, but for now, Patrick will create what he needs from S3 data. He plans to have the new classes available for use by other DMT authors by the next detchar telecon in two weeks.


• Status of DMT monitors under substantial development / revamping / debugging:


• John Whelan / Mark Cenac / Brian O'Reilly: StochMon
  Marc reported that the StochMon now works correctly, except for the implementation of the overlap reduction function, which should require another week or two of work. The monitor now provides to the DMT Viewer two time series: Omega and 1/Omega**2, along with a frequency series of the instantaneous power spectrum. The code has been tested on a LHO machine and will soon be tried out at LLO and placed into CVS.
  
  
• Tim Bodiya / Keith Riles: SpecMon
  Tim has been on vacation since the detector investigation camp where he gave a demo on the latest version. He will be putting the new code into CVS soon and asking John to create a standard executable for general use. Bill Kells has been trying the program out and has given Tim suggestions for improving the GUI interface.
  
  
• Ken Ganezer: seis_blrms
  Ken is modifying the existing code to catch time step discontinuities.
  
  
• Sergey Klimenko: BurstMon
  Sergey awaits Patrick's new calibration class and will ready the code according to the new template linked above. He mentioned having trouble keeping up with data in real time, apparently because of the long time strides he has been using (10's of seconds). About 40% of the data is lost. The loss is not critical, since the monitor is a sampling one, but it means that trend files would be full of undesirable gaps. He is working with John to see if adjusting memory buffer sizes can eliminate the losses (CPU consumption should not be an issue; data flow seems to be the problem). He expects the new code to be placed in CVS in about a week.
  He also stated that if there should be a shortage of available CPU time during the S4 run, he recommends disabling the WaveMon monitor for online use and running it slightly offline instead. KR didn't like the idea of disabling the only online DMT monitor that looks explicitly for correlated transients in AS_Q and auxiliary channels. He reminded everyone that a standing committee chaired by John is charged with deciding which monitors to run during data taking.
  
  
• Steve Penn: BicoMon and BicoViewer
  The new heterodyning option in BicoViewer for zooming in on regions is now working, but a new bug has arisen that (mysteriously) prevents reading of offline frame files. Steve is working with John to sort the problem out. The new "movie" option of BicoViewer is being used by high school students in New York near Steve's campus as part of a semester-long class project led by their teacher who spent part of the summer working at LHO. Steve expects the students to start confronting the data seriously in the latter part of the coming fall semester.
  
  
• Giovanni Santostasi: PulsarMon
  Giovanni was unable to attend the telecon, but reported he will be spending the weekend at LLO to work on the monitor.
  
  
• Rauha Rahkola: SuspensionMon
  Rauha is resuming work on the monitor and plans to have the trend-writing bug diagnosed and fixed in the next two weeks.
  
  
• Natalia Zotov: PTMon
  Natalia has run all of the S3 data through the monitor, using condor, and has added detected SNR to trigger info.
  
  
• John Zweizig: LSCMon et al
  No substantial work on monitors lately. .
  

• Next detchar telecon: Friday September 17 at 1:30 p.m. EDT (DMT software & S2/S3 investigations)
