Search for Short Transient Gamma-Ray Events in SPI Experiment Onboard INTEGRAL: The Algorithm and Results

We consider the possibilities for a searching and analyzing various short transient gamma-ray events in the archival data of the SPI experiment onboard the INTEGRAL observatory. The problems of the raw observational data processing, including the search algorithm and the method of automated classification of detected events based on a set of various criteria are discussed. The results of the analysis of the SPI/INTEGRAL archived data obtained for the period 2003–2010 are presented.
