1 Detector characterization for burst searches by resonant detectors F. Salemi Italy, INFN and University of Ferrara for the IGEC2 Collaboration The 10th Gravitational Wave Data Analysis Workshop (GWDAW-10) December 14 th to 17 th, 2005 Brownsville, Texas.

2 Outline AURIGA  Spectrum  Vetoes  Event Search  MonteCarlo Software Injections Raw Data exchange:  First step toward the Cross-validation of analyses  Results produced by AURIGA Data Analysis IGEC2 S hh Event Search MonteCarlo: Time of arrival uncertainties estimation Hardware Injections GWDAW10 - December 14 th, Brownsville, Texas

3 AURIGA output: the modes Typical recent spectrum averaged on 8 consecutive hours Main modes = mixing of bar, transducer and electrical modes: 865, 914, 955 Hz at thermal noise level GWDAW10 - December 14 th, Brownsville, Texas
