Coherent network analysis for triggered gravitational wave burst searches

Understand

Searches for gravitational wave bursts that are triggered by the observation of astronomical events require a different mode of analysis than all-sky, blind searches.

• For one, much more prior information is usually available in a triggered search which can and should be used in the analysis.
• Second, since the data volume is usually small in a triggered search, it is also possible to use computationally more expensive algorithms for tasks such as data pre-processing that can consume significant computing resources in a high data-volume un-triggered search.
• From the statistical point of view, the reduction in the parameter space search volume leads to higher sensitivity than an un-triggered search.
