(J. Chiang 4/23/07) We need to establish a maximum time interval size to facilitate the reading of the FT2 files by our various tools. For GRB analysis, the burst duration may be much less than 30 seconds (or whatever the nominal time interval is) and if one uses the extended filename syntax to filter on FT2 data using the inferred burst time boundaries, (tmin, tmax), using a filter string "(START >= tstart) && (STOP <= tstop)", and if those boundaries lie entirely within a time interval, this filter string will return zero intervals. To guard against this we would need to do something like "(START >= tstart-maxIntervalSize) && (STOP <= tstop+maxIntervalSize)".
