TJD 11540 = 28 December 1999

	TTE, TTS, MER data, Trigger Number 7922

The data in the TTE, TTS, and MER files for 
   trigger number 7922  at  TJD/SoD = 11540/16082
seem to be corrupted.  The reason is not understood but may be a hardware
problem.  This had happened before.

The data in the TTS and MER files seem to be for the preceding event (no. 7921).

The TTE data seem to change from the trigger detectors to another detector. 
The trigger detectors (DSELB) were 2, 6, and 3.  The first board of TTE
(pre-load time) has all detectors as it should.  The first three packets and
part of the fourth packet of the second TTE board (post-load time) have 
detectors 2, 6, and 3 as they should.  However, part of the way through the
fourth packet and for the remainder of the TTE file, only detector 0 appears.
Detector 0 is not one of the trigger detectors for number 7922 and not even
for the preceding event, number 7921, whose trigger detectors were 3 and 7.
