Name: DMS2000
Sample Interval (msec): 2
Record Length (sec): 16.384
Details
Shot Sequence and time in headers do not match up with the shot/time entries in the ts.n files
Dates/times are zero for lines 01 (all), 03, 19, 19a, 23, 24, 29
LDEO has no additional information that would allow matching navigation with shots
LDEO has no information about source-receiver offset
There are no msecs in the headers. It is possible that the time is from the original SEGD general header which may differ from the true time
For some lines shot number is reset to 1 in the middle of the line
Lines 01, 03, 19, 19a, 21-24 were flagged as IBM Floating Point
Lines 20b, 25-49 were flagged as IEEE Floating Point
Line 28b contained only a partial trace after shot 138, trace 40. It is assumed to be incomplete.
