This is the Input-record selected for the 1st experiment using the Synapse
DGS package.....
It shows a common paper (of the thousands available at Spetsgeofizika...)
with 48 traces, 100 m far each. The main vertical lines are 0.1 s references-lines;
in between the 0.01 s lines ! The upper line is a Time-referenced line
(50 pps). Other technical info were written by hand on the original paper:
the Station and Profile's names, the magnification, the seismometer type,
etc... Normally the operators wrote the information on a standardstamp widely used in the former USSR.
