S3 and E11 Investigations:

• Calibrations -- S3  (Mike Landry, Gaby Gonzalez, Brian O'Reilly, Patrick Sutton, Xavi Siemens)
  Gaby reported that H1, H2, and L1 calibrations are very nearly final. Intervals flagged as having bad alpha/beta values will be available tonight (KR's note: the intervals were indeed finished that evening, allowing a version 4 S3 data quality segments release). The various files for the final S3 calibration will be posted during the coming weekend. The final L1 values were held up an extra few days by the discovery of an apparent discrepancy in open loop gain phase at 160 Hz, but it is now believed that discrepancy does not affect the 1-minute compilations of alpha/beta corefficients. The tracking of complex alpha/bet values with Xavi's demodulation code has permitted more stringent checks than in the past.

M6 Preparations and DMT Software Status:

• L1 status -- Brian O'Reilly
  The interferometer is performing well now after a difficult week of electronics and computing troubles. Low noise is expected in tonight's pre-run testing. A problems with mode cleaner wave front sensing was fixed recently, which was important because of a known shift in MC1 mirror that WFS can compensate. The plan for calibration is to measure test mass (DC) actuation Friday morning, to produce curves for the online DMT monitors. JohnZ will assemble the calibration file needed for EasyCalibrate. Gaby mentioned that she will be looking at the new alternative GW channel DARM_A (instead of AS_Q) to see if it has the expected better stability. Rich Riesen has a lot of visitor access cards available for persons visiting LLO over the weekend. KR wondered who would be taking over for Chethan Parameswariah, who departed LLO last week for a new position. PeterF reported that Rolf Bork and Alex Ivanov will be covering for Chethan until a new person is hired. Ashfaq Khan will also be available to help with some issues.
  
  
  
• John Zweizig: Infrastructure status (hardware & software at LLO)
  John has compiled and downloaded to the sites the new DMT version 2.10.2. Significant recent changes include new linear predictor filtering from Shourov that affects glitchMon and KleineWelle. There is also new code and config file for PTMon. SegGener will now generate 60-second science mode intevals instead of 200-seconds intervals, at the request of the online data analysis crew. A new version of PulsarMon with bug fixes is installed. John will work on getting the onling documentation links at LLO working correctly. He and/or Szabi will track down why the new LLO machine clearwater shows up on the LLO spi page, but not the global spi page. John hopes to move all of the LLO DMT machines into racks on Friday morning.
  
  
• Patrick Sutton: Calibration infrastructure
  Patrick started modifying SenseMonitor to read old alpha/beta values, but ran into the problem that he can no longer run the old or new versions of  SenseMonitor on the Caltech alter machine. Patrick spoke with Marc Cenac on the phone for a couple of hours to sort out why StochMon was unable to compile with EasyCalibrate. They found some bugs and makefile problems which Marc has fixed. StochMon-with-EasyCalibrate now compiles, but it hasn't been tested running on data yet. The plan for M6 is to run the old StochMon (no EasyCalibrate) and work on the EasyCalibrate version for E12.
  
  
• John Whelan / Mark Cenac / Brian O'Reilly: StochMon
  No report. See Patrick's remarks above.
  
  
• Ken Ganezer: seis_blrms
  Ken reported by e-mail that he is about to send JohnZ some new code with a bug fix. He believes the new seis_blrms correctly flags all data dropouts, and it has a 3-minute blanking of data following any dropout, to avoid filter ringdown red herrings.
  
  
• Sergey Klimenko: BurstMon
  Sergey reported by e-mail that he has fixed all known problems in BurstMon. He believes its new FOM plot of central frequency of loudes gltiches will prove useful. A test run for a couple of days at LHO revealed no problems.
  
  
• Giovanni Santostasi: PulsarMon
  Giovanni reported by e-mail that he has a new version of PulsarMon that he believes is free of memory leaks. It does not yet use EasyCalibrate, but Giovanni will be at LLO during M6 and working on a private version that does use EasyCalibrate.
  
  
• Rauha Rahkola: SuspensionMon
  Rauha has been having trouble seeing trend files at LHO produced by SuspensionMon with data viewer or ligo_viewer.  He can see by logging in that the trends are produced, but the frame builder does not seem to know about them. JohnZ will restart the version of SuspensionMon at LLO shortly.
