Data Quality Vetos in LIGO S5 Searches for Gravitational Wave Transients
Laura Cadonati for the LIGO Scientific Collaboration

The first year of the LIGO S5 run has seen intense activity in the LSC Detector 
Characterization team to assess the quality of the data and flag features that 
could affect astrophysical searches. The Glitch group is part of this effort, a 
venue for instrument experts and data analysts to collaborate in the 
identification of noise transients. 
This talk will describe some of the tools used in this quest and which data 
quality flags have been identified and used to veto loud noise transients in the
S5 burst and inspiral searches. Particular attention will be given to existing 
and planned veto conditions for transients that simultaneously appear in the
co-located Hanford interferometers.
