S3 and E11 Investigations:

• Calibrations -- S3 --  E11  (Mike Landry, Gaby Gonzalez, Brian O'Reilly, Patrick Sutton, Xavi Siemens)

Mike reported that the calibration team is nearing the end of the final (version 3) S3 calibrations. The H1 calibration is complete; one iteration remains on H2, and more work is needed on L1.
The E11 calibrations are complete with regenerated alpha/beta values. No further revisions on E11 functions or coefficients are planned. Mike mentioned that Matt Pitkin will be running the time-domain pulsar code on E11 in a Crab pulsar search to verify that the figure of merit estimate for Crab sensitivity returned by PulsarMon is consistent with what can be achieved in analysis of the non-stationary data.

M6 Preparations and DMT Software Status:

• John Zweizig: Infrastructure status (hardware & software at LLO)

John reported that the new LLO clearwater machine is now running the new astrophysical FOM monitors: BurstMon, PulsarMon and StochMon. For now he has used calibration configuration files he found lying around, but DMT authors should verify those config files are appropriate, and if not, provide new ones. New code John has received in the last few days include BurstMon and config files and SuspensionMon. John has added a parser to the DMT trend writer class that checks channel name format against a proposed new specification (see last week's telecon minutes). For now and until after S4, the code doesn't return an error code, but does print out a warning statement. A new DMT version will be tagged on Monday morning for ruse in the following weekend's M6 mini-run.
 
• Patrick Sutton: Calibration infrastructure

Patrick is starting work on a version of EasyCalibrate that reads and uses alpha/beta coefficients from a previous run of EasyCalibrate, primarily for use in simulations.
 
• John Whelan / Mark Cenac / Brian O'Reilly: StochMon

Marc reported by e-mail that he is having trouble getting StochMon to compile with EasyCalibrate.


• Ken Ganezer: seis_blrms
  Ken reported he is working on a new version to suppress filter ringdowns.
  
  
• Sergey Klimenko: BurstMon
  Sergey has fixed all of the problems reported in the E11 run: trend files are now written correctly (minute- and second-trends), and dmt viewer plots no longer appear to violate causality by reporting the history of the future. John will check with Alex Ivanov to find out how both minute and second DMT trends can be seen in the data viewer. BurstMon now reports a brand-new figure of merit, one requested by Fred Raab, the central frequency of the loudest glitches in a given time interval (1/minute). Sergey is having some trouble running with EasyCalibrate and will talk offline with Patrick to sort it out.
  
  
• Giovanni Santostasi: PulsarMon
  Giovanni believes he understands part of the problems seen in the online running of PulsarMon and will be doing more tests this weekend at LLO.
  
  
• Rauha Rahkola: SuspensionMon
  Thresholds have been raised slightly to reduce false-alarm rates. Verified definitively that SuspensionMon trends are not visible in the data viewer.

• KR wondered what LHO plans are for E12 running. Fred reported that some running will be done, but probably for all of E12. Some recent running over the xmas holidays gave 80% duty cycle when unattended. A recent early morning period yielded a 7-hour lock stretch at a very nearly constant inspiral range of 7.5 Mpc, using three AS photodiodes. Adding a 4th photodiode (hoped for E12) should bring range up another 12% or so.
