Output of LSHA.OUT

Among the results of LSHA.OUT, there is a value of ANALYSIS OF EXTERNAL MODE HORIZONTAL VELOCITY. Among them, on which axis is the value of ‘ANG’ of each symbol derived?
(SYMBOL, TCP, MAJ, MIN, ANG and PHE appear in turn.)
Is it counter-clockwise or clockwise? I’m curious as to which axis it comes out on.

Hello Geehjh,
For the analysis of external mode horizontal velocity, the “ANG” angle is in degree unit and its initial side is on the positive x-axis. Positive rotations are counter-clockwise.

Sincerely,
Kien
