    DSELB in MER, SHERB, and TTS data, Trigger Number 6811

The DSELB value (triggered detectors) in the auxiliary data in the 
MER, SHERB, and TTS files for trigger number 6811 at
  start time = SCTIME(3,2,1) = (55B8,A2C9,AE5D)
             = TJD/SoD = 10972/41673.6975
   load time = SCTIME(3,2,1) = (55B8,A2C9,B520)
             = TJD/SoD = 10972/41673.7245
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 6811 is "-----2-0" = "00000101" which becomes the hex value 5.
The correct DSELB value in the other files for trigger number 6811 
is "7-5-----" = "10100000" which becomes the hex value A0.

The DSELH1,2,3,4 values in all files are  7,6,5,4.

The count rates in the MER data seem to be valid although the file is
not complete (492 of 512 packets).

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.

There seem to be data in the SHERB file, which is not complete (344 of
384 packets).  It is not yet known whether the data are valid.
