Аннотация:The strategy for detecting collapsing stars in the Galaxy using a pair of instruments including theOGRAN optoacoustic gravitational detector and the BUST neutrino scintillation telescope, located in theground laboratories of the Baksan Neutrino Observatory, Institute for Nuclear Research, Russian Academyof Sciences, is discussed. A key element of the strategy is the search for correlated responses from both detectors,the so-called search for neutrino-gravitational correlations. The efficiency of various algorithms for jointdata processing, including analysis of the CH1987A event, is assessed. The processing technique is illustratedusing the current output signals of the mentioned instruments.
