Near-real time data access

You can find in the following directories the data of the iOSG-023 recording at Strasbourg, J9 (France) and former data from SG C026, data from the OSG-060 recording at Djougou, Benin (Africa) and data from the iOSG-024 recording at Rustrel, LSBB (France). iOSG-024 was funded by the EQUIPEX MIGA (Matter wave-laser based Interferometer Gravitation Antenna) project and by the European FEDER 2006-2013 (PFM LSBB - Developpement des qualites environnementales du LSBB).
