And when we broke and beat them, out-wiled them, and out-ran,
I was the proud grey stallion that thundered in the van !

Last but not least, QCD is our playground for exploring strongly coupled gauge theories; lessons learned here will help in understanding other strongly coupled theories (i.e., almost any New Physics model, perhaps even gravity).
Moriond QCD 2002: Theoretical Summary
In order to avoid the possibility of statistical bias, potential veto conditions were studied using only a “playground” data set comprising about 10 % of the collected data, selected by hand to give a sampling of different degrees of non-stationarity observed in the detector noise at different times.
Vetoes for Inspiral Triggers in LIGO Data
This playground data was not used in the calculation of the inspiral rate limit.
Vetoes for Inspiral Triggers in LIGO Data
Numerous interferometer control and environmental monitoring channels were examined at times when the inspiral templates reported triggers during the playground section, in order to look for correlations.
Vetoes for Inspiral Triggers in LIGO Data
What was initially helpful was to use the inspiral template triggers, found in playground data, and to inspect candidate channels at these times.
Vetoes for Inspiral Triggers in LIGO Data
The playground data was then used to judge the relevance of other potential data quality flags, leading to two additional data quality vetoes.
Vetoes for Inspiral Triggers in LIGO Data
This definition of the playground ensured that it was representative of the entire run; for instance, it included some data from all times of the day.
Vetoes for Inspiral Triggers in LIGO Data
These results are from the S2 playground data.
Vetoes for Inspiral Triggers in LIGO Data
Presented is a sample time-trace (from the S2 playground data) of the interferometer’s gravitational wave signal channel, L1:LSC-AS Q, after high-pass filtering, along with the signal from L1:LSC-POB I.
Vetoes for Inspiral Triggers in LIGO Data
We have repeated the veto study using a preliminary list of BBH inspiral triggers in the S2 playground data. L1:LSC-POB I again appears as a good candidate veto, with efficiency roughly comparable to what was measured for the BNS case.
