Proton Decay Background Study :

After the collaboration meeting, we found some problems in the 'final separation program'. Therefore, I moved the official plots into work-in-progress(2001/Jun). See the latest official plots in official plots(2001/Nov-Dec). Sorry for inconvinience. (S.Mine, 2001/Dec/07)

UN-OFFICIAL plots are found in "work-in-progress".
