P_SOURCE_START_TIME (PTY_SOURCE_START_TIME) | (DDL) |
Defines the time of the event responsible for the activation of each source implied by the nodes in a 1D grid. Note that the physical source may or may not actually activate at this time. This is the time associated with the many activities revolving around the activation of each source but only one source will be activated at each time. The grid must be the same as was defined by attribute source event uid in the associated seismic geometry set. The times are relative to attribute origin time.
