Description
ECLAIRs, the leading instrument onboard the SVOM mission, is tasked to autonomously search for Gamma-Ray Bursts (GRBs) and other high-energy transients within its wide field of view ( ~2 sr) in the 4-150 keV energy range. To complement the onboard detection capabilities and to take advantage of a better understanding of the instrumental context and huge computing resources, an offline trigger (OFT) pipeline performs blind searches, making use of data as soon as they become available on ground. Targeted searches focusing on multi-wavelength and multi-messenger external inputs will also be integrated into the OFT pipeline.
In this talk, we will present the overall architecture of the OFT pipeline, outlining various methods executed simultaneously to search for high-energy transients, including a detection method based on wavelet decomposition. A Machine Learning based detection method is also under development. First OFT results on in-flight ECLAIRs data will also be presented.
