These are examples of 2D views of a SEGY file. It use to analyse the contents of the file. It is possible to display informations on trace data and headers.
The small green triangle allows the selection of a trace from which header values can be displayed. Attributes are data dependent. A default set is defined for a SEGY/SU file.
Trace headers can be displayed above the seismic. Each selected header has its own axis. In the following example, the source coordinate ( src_x_scaled ) is shown in red and the group coordinate ( grp_x_scaled ) is shown in blue.
The red rectangle defines the area of interest used to compute the frequency spectrum. As you move the rectangle, the spectrum is recomputed instantly.
