Travel time table quality control (PSDM stage)
TT viewer is an auxiliary module that performs only quality control of travel time table, which is used as input data for depth migration process (Kirchhoff PreSDM - file in/out - migration TT). For example, in case of an issue with migration execution (or resulting CIG gathers) we can use TT viewer to make sure everything is correct with travel time table data set: there is no only zero (all samples 0) or some other incorrect TT data behavior. TT file is calculated by Time table calculation for tomo update, Time table calculation.
File name TT - input trace time table file (TT format).
Show tt data - enable for TT visualization, otherwise visual vista items will be empty.
Number of threads - amount of treads for calculation, By default: N-1.
Skip - switch-off this module (do not use in the workflow).
Header table - table with trace headers.
Apprx output size - approximate size o the output Time Table file on the disk.
Calculated bins - how many bins were calculated.
TT type - travel time table type: binary or seismic (*.gsd).
Sample ratio - travel time table sample ration.
Samples count - number of samples of travel time table.
There are no action buttons and Visual Vista Items.
The workflow example:
There are three visual vista items: 1) location map where w can do CMP point selection for its TT visualization, 2) header table and 3) image point gather:
