Present:

E10 & S3 Planning:

• Interferometer status (Rick Savage - LHO, Szabi Marka - LLO)

H1 has not changed much since last week, with inspiral ranges around 1.5-1.7 Mpc. There is still a glitching problem that is not yet understood, with a rate of about once every two minutes. H2 is now producing inspiral ranges above 400 kpc, better than seen in S2, although its wave front sensing servos are not quite complete. Sample spectra: H1 H2 .

L1 is still struggling to return to S2 sensitivity (see notes below on E10 run plans).

• Scimon shifts - KR

KR is still looking for volunteers to take four unclaimed LHO expert shifts, most of them occurring around the time of the LSC meeting at LHO (since last week LIGO-CIT has generously volunteered for three of the original seven unfilled shifts). If volunteers cannot be found by early next week, the slots will be re-assigned, based on FTE counts.

During E10 at Livingston, the middle of the night will be devoted to commissioning with scimon work in the early evening and later morning (pre-dawn) hours. Mike Zucker has asked for flexibility in planning, to deal with the troublesome interferometer.


• Calibration plans - Mike Landry
  The calibration team's plan presented some weeks ago remains in effect at LHO, with most measurements expected to be done by the start of E10 tomorrow. Work at LLO must, of course, wait. There was some discussion of how to inject calibration lines. Bruce Allen has provided for the option of injecting them along with pulsars (see below), at Szabi's request. It was decided to continue injecting lines separately and to merge the pulsar and stochastic injected signals together on a single excitation channel. If problems with this arise, then Bruce's code provides a fallback option.
  
  
• Hardware signal injections - Peter Shawhan, Szabi Marka
  An outline of injection plans is described in a document . There will be continuous pulsar and stochastic signals injected during E10 and continuous pulsar signals during S3. The pulsar group will use Bruce Allen's new code to try injecting 10 pulsars, five of whose parameters will be quasi-secret in that some analysts will be asked to try to find the signals without looking at the posted parameters. Sergey Klimenko will be asked to track all 10 pulsars in the excitation channel (most will not be visible in short-time AS_Q integrations). Mike agreed to make sure Sergey gets the right numbers. Mike will also determine the injected amplitudes to give a variety of SNR's over the course of S3 in the H1 data. He and Peter will confer to make sure the H2/L1 injection files are made consistent with the H1 file. Peter mentioned that no new burst/inspiral waveforms have been provided for injection, but he knows people are working and expects to get those waveforms soon. Sukanta Bose is working on the stochastic injection code. It now works on linux, but not yet on solaris. Peter will be writing some new scripts to handle merging of the pulsar and stochastic injections. He will also be testing Bruce's code in the next 24 hours with actual injection turned off in the case of L1. Bruce mentioned that some parameters can be tuned to improve performance, if needed, and that his phone numbers are listed in the readme file.
  
  
• Reduced data set generation(RDS) - Philip Charlton, Isabel Leonor
  Philip reported on the progress of the RDS mock data challenge(MDC). The generation of RDS is working quite well at both sites, with levels 1, 2, and 3 being produced in parallel (1=several hundred channels, 2=AS_Q with excitations and downsampled gains, 3=AS_Q-only). Level 1 RDS can be produced at roughly twice real-time and the others at better than 10 times real-time. There are still  16 requested RDS channels not in the site data streams (3 at LHO, 13 at LLO). Chethan confirmed that the LLO channels will be in place by tomorrow. The transfer of generated RDS has been more problematic, where a hybrid of old and new LIGO Data Replicator (LDR) code has been used, with mixed success.  Data has been transferred to Wisconsin, Penn State, and MIT, but with several-day latency. It is thought that transfers will improve shortly, though, to a few-hour latency. It is planned to delete the MDC backlog tomorrow and get the E10 data flowing as soon as possible to Tier 2 centers. Separately, there is currently a technical problem in getting adequate network throughput out of LLO to CIT.  Stuart Anderson and Igor Yakushin are working on the problem. [Editor's note: Philip provided a more detailed summary of the mock data challenge on October 17.]
  Regarding channel selection, Isabel has posted a tentative RDS channel list . She mentioned having removed the ETMY excitation channel and restored the DARM excitation channel. She will be adding a handful of slow weather channels Robert Schofield has requested. She asked for clarification on what RDS channels the pulsar group wants in level 2. KR suggested storing the same channels needed for rerunning SenseMon on RDS. Isabel will circulate a proposed list.

DMT Software Status Review:

 
• Status of DMT infrastructure

 
• John Zweizig: Version updates, deadlines, etc.

John has received new code for PTMon, SuspensionMon, and SenseMon. He expects shortly to receive a modified LineMon (see below) and BicoMon (see below). Things are shut down for the moment at LLO because of LDAS disk remounts, but John expects to have everything back to normal later in the evening. Chethan mentioned having had troubles with various figure of merit displays. John thought thought those problems were due to T3 disk changes and should go away tonight. The cvs DMT version tag for E10 will be 2.70. There may well be another tag version number before the start of S3. The new DMT version will be compiled with a new framecpp version that itself will not be tagged until tomorrow. SpectrumArchiver (see below) is not yet checked into cvs and cannot yet be run under the process manager. KR will contact Tim Olson to see what his plans are w.r.t. using the new data synchronization class. Peter Shawhan mentioned that new LDAS database files will be defined specifically for the E10 and S3 runs.


• Status of DMT monitors




• Dave Chin / Tim Bodiya / Keith Riles: LockLoss and ServoMon/SpecMon

KR reported no changes in LockLoss/ServoMon since last week. SpecMon will be exercised at LLO once more this weekend, to evaluate fixes made since the M4 mini-run.


• Ken Ganezer: seis_blrms (report by e-mail)
  The Dominguez Hills group is looking into taking responsibility for seis_blrms. Ed Daw has been contacted, and Ken is reading over the documentation.
  
  
• Masahiro Ito: glitchMon
  Aside from a couple of changes in config files, there have been no recent updates. 



• Sergey Klimenko: LineMonitor and WaveMon (reported by e-mail after the telecon)

Sergey has checked in a new version of LineMon into cvs that supports an additional straight-heterodyne option for line tracking. The code seems to work, but he is carrying out further tests now. Sergey will await Mike's list of frequencies to track.


• Szabi Marka: IRIG-B, TimeMon, and ShapeMon 

No changes to IRIG-B or TimeMon. Szabi has added channels requested by Robert Schofield to ShapeMon to watch for channel hopping. Some of those channels have much higher sampling frequencies than the seismic channels ShapeMon has looked at previously. As a result, some minor coding changes are needed, which Szabi hopes to have done soon.
Alarm silencing has been tried out by several persons and comments given to Szabi. There were complaints about the program's handling of alarms that disappear and then come back again. A request was made that silencing have two options, silencing of a single instance of a given alarm type, and silencing of all alarms of a given type. Szabi will try to implement the option before S3. He may also change the alarm sound (presently a bird cry).


• Tim Olson: SpectrumArchiver (report by e-mail after the meeting)

There have been no updates to the code this week. Tim was unaware that John's new data synchronization class is now available for use.


• Steve Penn / Vijay Chickarmane: BicoMon / BiLinMon

Steve is tracking down one last bug in BicoMon. He has a new version (for S3, but not for E10) that allows monitoring of multiple channels with one program. He collected some suggested seismic channels from Nelson Christensen to monitor the cross-bicoherence of with AS_Q at LHO, and suggested frequency pairs from Vijay Chickarmane to monitor the auto-bicoherence of in AS_Q at LLO. Steve hopes tonight to send John scripts to run BicoMon under the process manager. .


• Brian Stubbs: SuspensionMon (report by e-mail)

New code has been given to John. Although minute trending is not quite working yet, Brian will try to finish debugging it this weekend so that Rauha can try it out next week on shift, in the hope of getting a final version ready for S3. A summary html file is not yet quite ready. Thresholds for channels have been set for both sites.


• Patrick Sutton / Mike Ashley: SenseMonitor / LineAmp and RayleighMonitor

Patrick has checked the latest SenseMonitor into cvs and has spent time in the last week updating the documentation. He has also started dusting off Rayleighmonitor. There was some discussion about how best to run RayleighMonitor in the control room. Based on past experience, it's best to run the program on sand/stone or delaronde and display the graphics to a pc in the control room. Rick will check on Dave Barker's plans for LHO, and Keith will check with Chethan for LLO.


• Natalia Zotov: PTMon

PTMon has no known bugs, but new features have been added that haven't been fully tested. The program now produces minute trends and a summary html file. Natalia will be at LLO starting tomorrow to do further testing. John mentioned that DaveB and Chethan need to be informed about PTMon (and other new monitors) with minute trends so that the network data server config file is updated. Otherwise, the data viewer will not be able to serve the trends. John will go systematically through the new monitors to make a list of what's needed..


• John Zweizig: BitTest,  DataQual, HistCompr, PSLMon, SatMon, and SegGener

No recent changes, but some minor work planned, particularly for the new SatMon

A.O.B.

• Next detector characterization telecon: Friday October 24 at 1:30 EDT to review what was learned in E10
