The Active Seismic Line is the seismic line to which line tie adjustments will be applied, and it is adjacent to the reference seismic line. The cursor position on the seismic when one of the line tie functions (bulk shift, amplitude scaling, phase rotation, polarity reversal, or Complete with Diagnostics) is selected determines the active line.
The name of the active seismic line appears in the title box of the Diagnostics window.
