Data Analysis is the final and most important aspect of the chain of activities performed in a GWD. The faint signal must be extracted from the output of the interferometer, embedded in the background noise. Key ingredients of this activity are the modelling of the expected signal, filtering of the data stream, vetoing through a deep knowledge of the technical aspects of the GWD, correlation with the output of the GWD in the world wide network and statistical analysis. High performance programming and parallel computing (GPUs) are crucial competences in this sub-programme.
