Burst signal injections during S3

Burst signal injections during S3

• The Burst group wishes to continue to inject
  burst waveforms into DARM or ETMX/ETMY, just
  before, during, and after S3.
• Test Event Trigger Generator sensitivity, time,
  frequency, amplitude resolution
• Test that hardware and software injections
  produce the same response in the burst detection
  pipeline calibration dependent!
• Monitor the stability of the response of the
  detectors/pipeline to bursts, as a function of
  time throughout the run.
• Check the safety of veto channels.
• Test correlation/coincidence techniques
• Minimal need a crude swept-sine of
  sine-Gaussians, as was done for S1 and S2.
• The more injections, the better! Quantitative
  test of calibration.
• Injections into DARM are fine further
  interesting but not essential studies are enabled
  by injecting into ETMX and ETMY in different
  strengths per the antenna pattern.

S2 Burst Hardware Injections

• Short, narrow-bandwidth signals (sine-Gaussians),
  sweeping over detection band.
• amplitudes span range from "barely detectable" to
  "large, but not so large as to break lock".
• The higher the statistics, the better!
