We present the status of the Virgo analysis pipeline dedicated to the search for coalescing binary signals, focusing on methods based on prior knowledge of the signal waveform. The pipeline includes two partially independent search methods: the multi-band template analysis (MBTA), which is original of Virgo and exploits the chirping behaviour of the signal, and a distributed implementation of the classical matched filter procedure (Merlino), based on robust MPI code. We discuss the application of the search methods to the analysis of data acquired during the Virgo commissioning run C5, which allowed us to perform tests and partially validate the methods and code.

Abstract
We present the status of the Virgo analysis pipeline dedicated to the search for coalescing binary signals, focusing on methods based on prior knowledge of the signal waveform. The pipeline includes two partially independent search methods: the multi-band template analysis (MBTA), which is original of Virgo and exploits the chirping behaviour of the signal, and a distributed implementation of the classical matched filter procedure (Merlino), based on robust MPI code. We discuss the application of the search methods to the analysis of data acquired during the Virgo commissioning run C5, which allowed us to perform tests and partially validate the methods and code.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
