Utilities sub-menu:
Liner Pol - apply eigenvalue polarisation analysis for current time window in particle motion viewer using real covariance matrix (method determined by -multicomp.polarisation.type SeisGram2K parameter, default=COVARIANCE).
A vector showing the best-fit linear polarization is displayed in the viewer.
This vector can be repositioned by dragging the circular handle at either end of the vector.
Apply azimuth to gather - the current linear polarisation azimuth is applied as the rotation angle for the current gather in the main SeisGram2K window. If unselected, gather rotation angle is reset to value before selection.
