Table for TTE Data Completeness for Short Bursts

From simultaneous visual examination of preb+discsc data (64 ms resolution) -- comprising 2.048 seconds prior to trigger time and several seconds after -- and tte data (rendered to 8 ms resolution), a tte "completeness" rating was determined for each short burst (T90 <~ 2 s) with tte data. The ratings (A=>E) are described in the following Legend. The Table follows immediately, with these entries per burst: ordinal number, BATSE trigger number, completeness rating and comment where applicable.

Legend:
(A) Entire burst within TTE window; or, negligible portion of onset missed
(B) Most of burst within TTE window, including interval of peak intensity
(C) Part of burst within TTE window, but NOT interval of peak intensity
(D) Minor portion of burst in TTE window
(E) TTE window missed burst entirely
