KleineWelle

Installation

• KleineWelle is contained in the gds-minitor packages which is available from LIGO's apt/yum repositories.

  debian> apt-get install gds-monitors
  RHEL> yum install gds-monitors

• T. Yamamoto installed KleineWelle all client workstations (k1ctr*) and k1sum*.

How to use

• Technical Document of KleineWelle is [1].

• KleineWelle is available as a kleineWelleM command.

  > kleineWelleM  parameter_file  -inlist  file_list

• The format of parameter_file is as follows (T. Yamamoto cannot find the sample of the format).

  stride 16
  basename K-KW_TRIGGERS
  transientDuration 4.0
  significance 2.0
  threshold 3.0
  decimateFactor -1
  channel K1:FOO-BAR_BAZ
  channel K1:BAR-BAZ_FOO

• The format of file_list is a simple list of the file path (not a LIGO cache file format).

  /path/to/K-K1_C-1000000000-32.gwf
  /path/to/K-K1_C-1000000032-32.gwf
  /path/to/K-K1_C-1000000064-32.gwf
  ...

Trigger generation for DailySummary

• DailySummaryPage uses the trigger files using gwtrigfind for constructing the KleineWelle summary page.

• T. Yamamoto modified gwtrigfind because our computer environment is slightly different from LIGO's one.

  • According to the gwtrigfind code, trigger files should be generated in the /gds-k1/dmt/triggers

  • T. Yamamoto change to /home/controls/triggers (same as Omicron output directory).

• The KleineWelle job is automated using crontab on k1sum1.

  > crontab -l | grep KleineWelle
  10-59/15 * * * * /users/DET/tools/KleineWelle/Script/automation.sh /users/DET/tools/KleineWelle/Parameter/summary_test.txt > /tmp/auto-kleinewelle.log 2>&1

• When you want to add some channels for the KleineWelle search,

  • 1) add channel name to DATA CHANNELS line of /users/DET/tools/KleineWelle/Parameter/summary_test.txt
    or 2) add new job to crontab

    > crontab -e
    10-59/15 * * * * /users/DET/tools/KleineWelle/Script/automation.sh /users/DET/tools/KleineWelle/Parameter/summary_test.txt > /tmp/auto-kleinewelle.log 2>&1
    10-59/15 * * * * /users/DET/tools/KleineWelle/Script/automation.sh /path/to/your_parameter.txt > /tmp/auto-kleinewelle2.log 2>&1

  • In order to use trigger results on SummaryPage, use K-KW_TRIGGERS for the basename parameter.
