  1. Data Quality FlaggingS5 Elog Entries Tiffany Summerscales Andrews University March 2007 LSC/VIRGO - Detchar

  2. Issue: Important DQ Information in Elogs • Elogs - Electronic logs for both Livingston and Hanford sites • Record of observations made of environmental and detector issues that could affect data quality • Need a list of “flags” based on these observations • Date of observation may not be the same as data affected • Computer-readable list March 2007 LSC/VIRGO - Detchar

  3. Work Done So Far • Webpage http://www.andrews.edu/~tzs/detchar • Two Andrews undergraduates - Nick Valles and Jon Van Ornam started listing DQ flags • ~ 2 months at each site March 2007 LSC/VIRGO - Detchar

  4. Work Done So Far March 2007 LSC/VIRGO - Detchar

  5. Work Needed • Fill in the rest of the webpages! • Translate elog observations to data quality flags • Record start & stop times, segments affected, etc • Call for volunteers March 2007 LSC/VIRGO - Detchar

  6. Ideas for Improvements • Increase automation for generating web pages • Switch computer-readable format to ilwd • ilwd - xml with certain headers • ilwdread - MATLAB function in Ligotools • ilwdwrite - MATLAB function to write ilwd • Any suggestions? March 2007 LSC/VIRGO - Detchar
