• Calibrations (Mike Landry, Gaby Gonzalez, Brian O'Reilly)
  Gaby reported on two calibration news items: 1) It is now thought that the sign discrepancies observed in S4 hardware injections can be explained by inconsistent definition of loop feedback sign in the actuation functions used. A report is under preparation. 2) Myungkee Sung has been looking at fast fluctuations in alpha/beta coefficients derived from Xavi Siemens's h(t) code. He sees what appears to be aliased peaks that may have a small effect on the alpha/beta values derived at 1 Hz and 1/minute. Xavi will likely apply tighter filtering in the next iteration.
  
  
• S4 data quality flags (John Zweizig, Keith Riles, Peter Shawhan)
  Keith briefly reported on the recent release of version 8 S4 data quality flags. Most issues have already been discussed in earlier detchar telecons, but one recent contribution was correction of some L1 segments for which version 3 alpha/beta values were unavailable.

DMT Software Development:

• John Zweizig: Infrastructure status (hardware & software)
  John is working to make a DMT 2.10.5 release, which include new DMT trend names for many DMT monitors (see below). He has run into some trouble with automake, especially w.r.t. the FFTW library on SPARC machines. He is also having trouble with the spi page and will enlist Szabi Marka's help. He asked that any last-minute changes for this release be given to him by the end of the afternoon.
  
  
• Keith Riles: Status of DMT trend name changes
  Keith summarized the status of the DMT trend changes. Nearly all monitors have updated their names in the CVS archive. It is hoped that by next week, nearly all monitors will be up and running again at LHO. Daniel declared that there was no need for MultiVolt and DeltaMuSigma to continue operation; so those were removed from the status list.
  
  
• Soma Mukherjee / Roberto Grosso: MNFTMon
  Soma reported that Roberto is travelling, but will be back in touch next week. They are planning to travel to LLO in mid September to finish shaking down MNFTMon. There was some discussion of which output format would be most useful. Minute trends of band-limited noise estimators including min/max/rms seemed useful, along with a trigger rate for threshold crossings.
  
  
• John Whelan / Mark Cenac / Brian O'Reilly: StochMon
  John reported that the new "double live" version of the monitor was running last week and should be ready for prime time soon. He is now sorting out some discrepancies in reported Omega sensitivities among single-live and double-live programs.
  
  
• Giovanni Santostasi: PulsarMon
  Giovanni reported that PulsarMon now compiles successfully with EasyCalibrate, and he will be testing it real-time this weekend at LLO (KR note: Hurricane Katrina derailed Giovanni's visit to LLO, along with many other things).
  
  
• Evan Goetz: PlaneMon
  Evan reported that PlaneMon still crashes occasionally on stone and has a clear memory leak (later tracked down to a bug in root graphics output). He has tried setting alarms, but has not seen them appear on the alarm page. He will start generating database triggers soon and requested that they be enabled in the trigger manager.
  

• John Whelan wondered whether the incomplete monitor CoherenceMon written by a graduating Loyola senior should be put into the DMT CVS tree, in the hope that another person could pick it up and complete it in the future. KR thought that was a sensible step for now, but that some of the code should eventually be put into the infrastructure part of the tree.
  
  
• Steve Penn reported that he now has the offline DMT code running on Mac OS X and asked for volunteers to help do further testing. Gaby volunteered.
  
  
• Next telecon: Friday September 2 (DMT software, S5 preparation, S3/S4 reports)
