S3 Segment Data Quality Repository

Peter Shawhan, Keith Riles

Quick link: most recent version of segment lists (at bottom of page)

This page has links to files containing information about science-mode segments in each detector during the S3 run. Science mode segment numbers for each interferometer were incremented each time a control room operator pushed the "GO" button to indicate start of science mode conditions.  A script (written by Peter Shawhan - info ) running every five minutes at the sites during the run produced the version 0 segment lists below. As for the S2 run, the segment numbers will be permanent, and many e-log entries refer to them by IFO and segment index (e.g., H1-27). This repository provides data quality summary information on individual segments, based on the work of many investigators. Data quality flags are listed for time intervals, and links to more detailed information are provided, where appropriate. Links to segment manipulation tools (e.g, segwizard) are also included. An extensive set of data quality investigations are described in detail on John Zweizig's data quality investigation page .

For each detector, there is an ASCII file ( S3H1_seginfo_work.txt , S3H2_seginfo_work.txt , S3L1_seginfo_work.txt, S3G1_seginfo_work.txt) which details any information learned about each segment which indicates that it is bad or potentially bad data. These files are maintained by hand. As information is learned and added to these files, they are periodically copied to different names incorporating a specific version number, and the information is also distilled and presented in a few other files:

Note that any given segment will retain the same numerical index in all versions of the lists, but it may acquire bad-flags indicating that it is bad or potentially bad.

The goal of this effort is to determine what data is suitable for searching for gravitational waves, and to provide this information in a machine-readable form. The success of this effort will depend on individuals examining the data, identifying effects which might cause the data to be bad, and then evaluating which effects are serious enough to disqualify data. Contributions are eagerly awaited; Keith Riles (kriles@umich.edu ) will collect this information and maintain the segment info files. ( Notes for maintainers. )
