The data reduction for the high-energy analysis was mainly for atmospheric neutrino events and proton decay search while the low-energy analysis was mainly for the solar neutrino events. The reduced data for the high-energy analysis was further filtered by other reduction processes and the resulting data were stored on disks. The reduced data for the low-energy were stored on DLT tapes and sent to University of California, Irvine, for further processing.
