    DSELB in MER, SHERB, and TTS data, Trigger Number 7755

The DSELB value (triggered detectors) in the auxiliary data in the 
MER, SHERB, and TTS files for trigger number 7755 at
  start time = SCTIME(3,2,1) = (5948,F74F,D85B)
             = TJD/SoD = 11428/63311.8654
   load time = SCTIME(3,2,1) = (5948,F74F,DF0F)
             = TJD/SoD = 11428/63311.8922
is different from the value in the other burst-type files which seems
to be the correct value.  The reason is not understood; however, the
MER, SHERB, and TTS files are the last types in the long readout.

The incorrect DSELB value in the MER, SHERB, and TTS files for trigger 
number 7755 is "--5432--" = "00111100" which becomes the hex value 3C.
The correct DSELB value in the other files for trigger number 7755
is "7-5-----" = "10100000" which becomes the hex value A0.

The DSELH1,2,3,4 values in all files are  5,7,1,3.

The MER data seem to be complete (512 of 512 packets).  The count rates
in the MER data may be valid and for the correct detectors (5+7).

There seem to be data in the TTS file, which is complete (512 packets)
but the Burst_Display program converts them to zeros. ???
It is not yet known whether the data are valid.

The SHERB data are not complete (370 of 384 packets).  It is not yet 
known whether the data are valid.
